Just saw this thread. I'm pretty sure our Adams' are the same family.
I don't have more information about William and Mary, but I do have a photo of their son, Elisha Adams and his wife Nancy McCann and their children (excluding their youngest, Linnie Adams, who was not yet born). If you email me, I will send you a digital copy.
Elisha was my great-great-grandfather. His daughter, Anna, had my grandmother, Paulanna HOSSLIN.
I have several other photos that may be related to your branch. Please send me an email and I'll see what relates to you.
