Robert,
I have Della & Henry in my file. I found them in the 1930 Ohio Census in Porstmouth. They list your father as Louis V, age 11/12 and living with them were Blanche's siblings, Chester, Earl & Mildred.

If you will send me your e mail address to sp1ke@windstream.net I will send you what information I have? My great grandmother was a Cremeans so I have lots of information on that side of the family if you are interested.
