Thank you for the information. I have all of that information. The first census you listed does not appear to be my David, however. I've confirmed his father was William and mother Anna, according to his death certificate I found. The others are my David and I have added that to my tree. Thank you again, for your help. I will continue my search and perhaps, eventually I will hopefully figure out which Marshall line we come from. And thank you for the leads on OH records, but I have found his death certificate as that is how I confirmed his mother's and father's names. I don't believe his parents lived in OH. From what I've gathered so far his parents William and Anna never left KY and I just can't find any information on either of them other than what you provided, too. I find several William Marshalls and even some William and Anna Marshalls, but none that I can confirm had a son named David. Thank you again, for your help.
