William Larned Marcy is in the book 'Healy History' by Mrs Carl W Carrier. Mr. Marcy is my half 4th cousin 4 times removed - I am of the Healy line. William's father's mother was Mary Healy of Dudley -she married Jedediah Marcy -, a granddaughter of Nathaniel Healy who was wounded in the Naragansett fight of King Philip's war. Nathaniel lived in Dudley and there is a Healy Road named for his family. I descend from Nathaniel's half brother Paul.
