If this is your current email, please respond and I can help fill you in on the family you mentioned on the post during the 40's and 50's.
My name is Steve and Ed Sossamon was my Great Grandfather.
The family you mentioned that relocated to the Porterville area was my Grandmother's family.She was one of the four sisters you mentioned and lived there in Porterville and Pixley in the mid 1940's with all the brothers you also mentioned.
I have the number to Ed's daughter who can fill you in on much more information than i remember about my Great Grandparents.They passed away in Martinez, CA when i was around 8 years old.
I do have some links that may help you on Ancestry.com though.
