Lowell Mather is a long time resident of Nantucket, whose family has lived on the island for five generations. Described as dim and eccentric mechanic/handyman, he works at the airport and is available to everyone when repairs are needed. Lowell claims that, while he is not an orphan, his brother is. He was married to a woman named Bunny with whom he had several children, but they divorced when Lowell learned that Bunny was sleeping around.
