Mr Nicely. I'm also looking for info on the Bias/Byas sisters that married the Nicely brothers, I know that Samuel Jr & Jonas are sons of Samuel Sr & Hannah, (Jonas & Jennie "Jane" are my line)
I have very little to go on, but this is what I have (most came from the net, some from census)

maybe this will help with some direction for you to go by, and maybe others will help to add or correct new info on this family, if you find out new things please post it for others.
