Here's one possibility. There is a family consisting of James Comstock 67, wife Jessie 46 and a son David Comstock 36 in the 1910 census for Trenton, Delaware, Ohio, USA .(District 57 page 16) They were all born in Ohio and James and Jessie had been married for 1 year (second marriage for both). Jessie is listed as having 3 children all living. David is obviously James' son but not Jessie's. If this might connect to you, I'll try chasing backward.
