My grandfather was named Granville Hodgdon, but he was younger than the Granville Hodgdon mentioned in your post. There must be a connection, however, because my grandfather's family was originally from the Boothbay area. According to my mother, his family moved from there to northern New Jersey when he was a child. My grandfather married Marion Doyle in Bayonne, NJ around 1940. Do you know if there is a connection?
