This is a bit of a mystery to me. I do not fully know the Espys here. I know a bit about one or two. By placing these items on my blog, and listing out the names, I hope someone out there - a confirmed relative of theirs, perhaps - will contact me and help me fill in the blanks.
Exhibit One - Mary Newman, William G. Espy
Exhibit Two - Glen Espy, A. Lee Espy, John Mark Espy
Exhibit Three - David Espy, Cathy Espy
