Hi Diane, Phoebe Pomeroy, born in Levant, Penobscot, Maine on September 23, 1819 was my ggg grandmother. Her father, my gggg grandfather, was William Pomeroy, born October 1, 1782 in East Hampden, Penobscot, Maine. Phoebe married George A. Smith in 1833. She died in Bangor, Maine in 1905. I haven't looked further back than William at this time, but there may be a link between my William and the William you are searching for. Where was your William born in Maine?
I have a photo of Phoebe, and if she is of your line, I'be happy to share it with you.
Hopefully, we can stay in touch as one of us may make a connection! If you wish to reply to my email, it is:email@example.com
