I am looking for information on my Great Grandfather, Henry John Gaab. He was born in Etna, PA, but listed Bessemer, MI as his residence on his WW1 draft registration card. He was married at the time to (possibly) a Catherine Skelly (from PA). They may have had a baby girl some time while they lived in MI. They also may have gotten divorced in MI. Henry was born 3.22.1888. Any help would be great!!
