David,I am sorry that I did not answer your question.I had an accident and was away from home and my computer for several months and missed a lot of my correspondence. I do not have any information on Marshal M. Diggs. I haven't done much research on the Diggs line. I decend from Ann's sister Keziah who married WilliamWatkins.Their daughter Elizabeth married Francis "Frank" Cole.This was my 3rd gr grandparents. Do you have any information about the Martha Snead who married a John Cole?
