I am researching the Slabaugh family history for my step-father. His grandfather's name was Eli Willis Slabaugh, born on 07/07/1888, and died on 05/05/1971. I know that he had 11 siblings and that his parents names were John Slabaugh and Susan Nisley. I have no dates or places on them. Any information anyone could share would be greatly appreciated.
