Mark R. Leith

Mark R. Leith passed away on April 26, 2026, at Spaulding Rehabilitation Hospital in Cambridge after a brief illness. He was born in Nashua, New Hampshire, on July 24, 1959, the son of the late Omer Leith and the late Rita Perron. He was also pre-deceased by his stepfather, Rodolphe “Duffy” Perron.

Mark lived in Nashua for most of his life, where he met his wife and the love of his life, Susan. The two married in 2000 and began their life together in Oak Bluffs, Massachusetts. There, they founded Martha’s Vineyard Excursions, a tour company that they built together into one of the most successful tour businesses on the island. Mark was happiest when he and Sue would go on adventures.

Mark will be fondly remembered by family and friends as a true jokester. No matter where he was, he was always making someone roll their eyes and laugh. As “Uncle Mark”, he loved making his nieces and nephews happy, especially when playing hide-and-seek. Mark was always the seeker and would often leave them hiding until they finally decided to come out on their own.

Mark was always there for his family and friends, regardless of the request. He devoted his life to building a successful business, being an exceptional husband, and being a dedicated brother, uncle, and friend.

Along with his beloved wife Susan, Mark leaves behind his sister, Melanie O’Bryant, and her husband, David ; his brother, Gerald Leith and his wife Shari; his brother Rod Perron and his wife Sylvie; and his brother Jude Perron, and his wife Ginny.

He was pre-deceased by his brothers Albert Leith and Dennis Leith.

In addition Mark leaves behind his nephew, Matthew Hebert, whom he enjoyed bringing up ; sister-in-law Tracy Collins and her husband Peter; sister-in-law, Diane Ekstrom, and her husband David; sister-in-law Michele Hebert; sister-in-law Debbie Maurais, and her husband Ben. He also leaves behind many nieces and nephews who will forever remember the joy Uncle Mark brought into their lives, as well as many lifelong friends and other relatives.
