Possible issue of DeBar and Cain
Here are two names that may be those of children born to JHDDB and Amelia Cain:
Jennie (Jeannette?) Gilmore, nee Diss DeBar (DeBar)--Married W.H. Carleton in Ohio (?)
Maude Laughlin nee Diss DeBar (DeBar) Parents of my grandmother, Marie Bennett nee Carleton. Marie was JHDDB's granddaughter.
Lived in Washington, D.C. area for many years; was living in the 1960's; had one daughter that I know of, but not her name. She was great aunt to my father, Harry Joseph Bennett, so the math would be right.
