Hi Ann, I am a descendant of John Adam Hixenbaugh who died in Alleghany Co., Maryland in 1793.His wife was Catherine Mathias. They had a daughter named Catherine who was born in 1782. I don't have any info on her marriage but John Adam's son Jacob migrated to Greene Co.,PA. Many Hixenbaughs from that family also migrated to Fayette Co.,PA. Perhaps youcan find our Catherine in PA.
