The Joseph Coley from 1941 I don't know if his middle name was Henry. I do know that the 1876 Joseph Coley was Joseph Henry Coley.
Is it possible that William Coley was the one who was the son of John Coley in Gnollis?
Also there are two Walkers in the picture: William Coley's wife Mary Walker and Joseph Henry Coley's wife Sarah Ann Elizabeth Walker. I'm going to be chasing after those two names... trying to figure out how "close" they were...
I don't get the Bloomer reference... based on the ages of the Bloomer Joseph... wet nurse?
