Mayor Flaherty described him as the "quintessential dedicated public servant and a wonderful member of the community".
“There’s been a huge tear in the community fabric. He became so involved in virtually every public aspect, like community events. Martin was incredibly bright and witty and a true Irishman.”
Last night, I got home to the worst news imaginable. My Uncle, Martin Nelis, was killed in a bike incident in California yesterday. Of course, the clan means a lot to me and to us and right now the Nelis/MacNiallais Clan is heartbroken.
