I am interested in the Martins of Grand Isle. My Martins were Caleb, Caleb and Caleb. The latter born in South Hero later married Lucy McCoy. Their son, Thomas McDonough Martin married a Mary born in Canada,Fr. They all lived in Clinton Co New York where Caleb, Lucy and the infant son of Thomas and Mary died. Thomas and Mary and 4 children moved to Iowa where two more children were born. Thomas and Mary died in Iowa and I believe are buried in Riverside Cemetery. I am hoping to find the maiden name of Mary. Any ideas? Thanks in advance.
