Thanks so much for posting this. A photo of a red covered bridge is part of the same group of photos. Do you have your family tree online? I have Nehemiah Matson, son of Enos Matson, on my Rootsweb tree, but no spouse for him, and no other information either. I'd like to fill in the gaps on my Enos Matson information.
I'm related to them in a complicated way through the Shugarts. Enos Matson, born about 1833 (son of the couple honored on the stone) had a daughter named Cora who married Judson Shugart, whose uncle Eli Lodge Shugart married Rosetta Angela Downing, whose father Heman Downing was a brother to my great-great-grandfather, Sumner Downing.
