Are you the Darrell Fanestill that was born in Great Bend, KS?
Do you have any information on a George W. Fail. He was born in Illinois but spent many years as a farmer in Davis Co., IA. He had a son Samuel W. Fail that enlisted in the 36th IA Infantry. After the war they ended up in Missouri. I am wondering if there is a connection between Isaac and George W. but can't seem to find much info on George.
BTW I have some more concrete dates for Isaac and Electa if you would like them.
