Currently trying to find the names of a friends half-siblings, who were from her father's previous marriage. The wife left and took the kids, never to be heard from again. The difficult thing is that she doesn't know her father's first wife's name.
Here is the info I have:
Fathers Name: William R. Shaver
Birth: 31 December 1939
He got his SS# issued in Oklahoma and lived there, but was adopted.
Kids Names: Kim and Kathy
Can someone suggest how to research? I was going to try to find the name of his first wife via marriage record and see if I could find an obit for her, which would hopefully list her children, but the only thing I can find on him at all is his DR in the SSDI.
