Hi everyone, I need some help on this one, my grandfather was born in Steelton PA 1898, he has always been William Decatur WINDLE, but it seems that maybe his real father was somebody SANSOM, or maybe his mother Jennie R. COFFIN wasn't married when he was born and he was given her last name until she married Isaac Harrison WINDLE, I think I should look for birth record but I'm not sure where or which name to look under. If anyone can help thank you.
