The historic brick building in downtown Boston was once one of the most important homes not just in the city but throughout the American Colonies. Built and owned by Founding Father John Hancock, the house operated as the headquarters for the Continental Army’s paymaster-general. At the height of the Revolution, it was the site where both patriotic and disgruntled Colonial soldiers received IOUs for their service. Today, it’s one of the 35 oldest buildings in Boston—and it’s for sale, tying it to Nantucket in a completely new way.

“This is the most exciting property that I’ve been involved with from a historical perspective,” said island native Dave Killen, a commercial real estate broker who is selling the Hancock House. “The background in growing up on the island and living through the conversion and the adaptive reuse of a lot of the historic buildings that hadn’t really been touched was a wonderful and unique education. When we get into conversations with property owners, builders and with the potential new owners or stewards of historic sites like this, having that background knowledge is very much a product of growing up on Nantucket. Having an early career here is critical to help drive a successful outcome in these conversations.”


It’s no stretch to say that for Killen, woodworking and historic preservation are akin to a family tradition passed down from generation to generation. Killen, a broker for LandVest, is the son of former Nantucket Select Board member Pam Killen and late builder and woodworker Bruce Killen. He’s the grandson of Sidney Killen, the man responsible for the original Christmas tree on the wooden so-called Killen Dory that’s become a fixture in Nantucket Harbor every winter.


Growing up, Dave Killen’s classroom was his father’s mill shop on Cliff Road, called Rock and Roll Millworks/Coskata Woods. Building doors, windows and trim, and sourcing material from reclaimed heart pine flooring and beams were like a final exam. He even built a few flat-bottomed skiffs with his dad at the shop, including one that served for a few years holding the family’s Christmas tree in the Easy Street basin. He was also instrumental in the restoration of an 1887 Victorian cottage on Milk Street, a massive project featured on PBS’ This Old House.

"As multigenerational locals that grew upon an island before it began to evolve into what it is now, there was a tremendous amount of traditional knowledge about how buildings were constructed,” Killen said. “That led to an interesting mix of tradition and creativity that is so important to the idea of preservation and adaptive reuse, whether we’re talking about a specific detail or a whole building.”


That education came in handy when he was tasked with selling the Hancock House for LandVest. “When I walked into [the Hancock House] for the first time, I was stunned by how much original work there was,” Killen said. “Growing up out here and working for my father and with some of the other builders of that generation, there were times when we were doing a restoration or renovation project when you’re digging into walls, and history is literally falling out of the walls.”

Since its time as a headquarters for the Revolution, the Hancock House has seen a wide range of uses. In the late 1700s, it was operated as an inn where guests included George Washington and French politician Marquis de Lafayette. For 150 years, the property was home to the longest continuously running shoe store in the country. It was also run as a restaurant at one point, and since 1976—200 years after Hancock signed the Declaration of Independence—it has been owned by the law firm Swartz & Swartz, which preserved the interior of the structure, including its two iconic Later Georgian first-floor rooms. The property is listed for $4.995 million.


The L-shaped building sits on 100% of the lot and is listed on the National Register of Historic Places. It has been lauded as one of the best preserved examples of the Colonial era. The original beam work is still in place throughout much of the house, along with beveled window casings designed to allow more light into the home’s interior and which are still in place well after electricity made the style obsolete. One room on the first floor has an original hearth with a beehive oven and an antique mantel. On the third floor, a hipped roof reveals exposed post-and-beam work, with a cathedral ceiling and original eastern white pine flooring. "We want to preserve it,” Killen said. “The stewardship component in all the conversations we’ve had has been key.”


“I think understanding the authenticity of these things, and understanding the level of craftsmanship and architectural detail—starting with the authenticity of the materials through the craftsmanship and the millwork—really helps the conversation with owners and with potential buyers,” he added. “They’re in this world of historic preservation and adaptive reuse, and there’s always this stewardship component with owners and potential buyers. The credibility of these conversations starts in the details.”

Written by Brian Bushard Photography by Kit Noble For the past 10 years, Katherine Jetter has been selling her jewelry at her shop on Centre Street, The Vault. But unlike most jewelry stores, she is not only selling her own jewelry, but the earrings, bracelets and rings of 30 other couture jewelers. This month, she is showcasing those jewelers at a residency at Ten Easy Street, which runs through August 15. “The purpose is to celebrate our community and create a place to bring all of our clients into a social environment where they can get to know each other and experience all the things I love and curate on a deeper level in a social environment,” Jetter said. “I love bringing people together and curating, so I have curated some incredible experiences.”  How did you get into the world of jewelry making? I didn’t come from a multi-generational jewelry house where I had the privilege of growing up with a safe full of gems and access to everything. I’m completely self-made, and the only way that I could shine in a very saturated industry was to really teach myself to be an expert on specific subjects, so that I could really come from a place of knowledge. What did that process look like for you? I studied and studied books on the history of jewelry making. I went to every possible trade show I could find. I’ve been going to the Tucson Gem Show since I was 24 years old and I ask 10,000 questions. The thing that really made me learn was that I was never afraid to say what I didn’t know—why is this amethyst a $10 per-carat stone, and why is this amethyst a $200 per-carat stone? I found allies and friends in the industry that would help teach me and educate me. As a young 20-year-old, I found people who loved their craft who were excited to teach a young person what they knew. I would do everything from finding the rock to going to the mines. That is what I think really is different about me. I made it my business to be an expert and to study what I’m selling, so that I’m not just a designer who’s taking pretty objects and putting them together. I’m being very thoughtful about everything from the ground up—where it starts, how it’s made, the engineering of the piece and the execution. When you’re selling a product, if you don’t understand from the ground up the integrity of the piece, it’s a very different sales process than if you’re coming at it from a place of workmanship. Even though I specialize in certain avenues, I also recognize that there’s something for everybody, and if it’s not something that I’m making, I still want to find you. I love doing that; it really is what excites me. I’ve never had an ego around it being my way or the highway. If I don’t make what you’re looking for, I will find the expert that does.

Interview by Paige Martino Photography courtesy of the Nantucket Historical Association Long before Greater Light became one of Nantucket’s most beloved historic houses, it was an aging 18th-century cow barn tucked away on what was then Bull Lane. Where others might have seen a weathered farm building, Quaker sisters Hanna and Gertrude Monaghan envisioned something extraordinary, transforming the humble barn into an exuberant home and art studio layered with salvaged architectural treasures, handcrafted furnishings and original paintings. They called it Greater Light . A hundred years later, Beverly Hall keeps HannaMonaghan’s spirit alive, putting on period clothes and performing as Hanna at Greater Light. “My feeling when I walked inside [Greater Light] for the first time was almost visceral,” Hall said. “One day during the process, I just got so immersed I said, ‘That house just needs someone to bring it alive.’ I just said it. I blurted it out. ‘Someone needs to be Hanna.’ The whole group turned around and said, ‘Beverly, why not you?’” Becoming Hanna meant immersing herself in Hanna’s memoir, filling pages with underlined passages, colorful notes and thoughtful observations tucked into the margins. She interviewed people who had known Hanna and spent countless hours researching both the Monaghan sisters and Greater Light itself. Along the way, she began recognizing unexpected parallels between their lives, particularly in their shared devotion to faith and the arts. “The attraction was immediate,” Hall said. “[Hanna] really sparked something within me, so I took it and ran with it.”

Written by Brian Bushard Photography by Kit Noble While they may not be household names in the true Hollywood sense, Nantucket’s summer population includes powerful producers, screenwriters and editors who are behind the scenes on the movies we all recognize. Indeed, Nantucket has an underground entertainment community that is in effect a hidden Hollywood.“I got involved in the Nantucket Film Festival before we bought a house on the island,” said Marc Resteghini, a producer with Amazon MGM Studios who executive produced the series Young Sherlock. “As I started to learn a little bit more about the festival itself, I started to realize there were a lot of people who either lived on the island or vacationed here from the entertainment industry.” Resteghini was named the new chair of the film festival this June. While Nantucket has a reputation for attracting politicians and Wall Street titans, lesser known is the fact that dozens of leaders in the entertainment industry have also found Nantucket as their summer refuge, just not the names you might know. “It’s like Sergeant Pepper Lonely Heart Club Band,” actor John Shea said. “We see each other but the last thing we want to do is talk about the film business. It’s more of a quiet acknowledgement of a fellow traveler thana fellowship.” “The Vineyard is where all the actors and the writers go, the creatives,” documentary film producer Annabelle Dunne added. Dunne summers on Nantucket. “I think a lot of people that work in Hollywood come here to be with their families, relax and enjoy Nantucket, not to network. But it is a small island, and sometimes when you take away the work component and you say we’re just getting together to get together, then things can happen.”
