I'm still searching for the maiden name of Catherine (Catharina)Halfhill and the date she married Dewalt.
I have located the names of all 5 children:
1. Anna, born April 13, 1807, married Pleasant Thomas
2. Catharina, born June 24, 1809, never married
3. Mary (baptised Maria), born October 17, 1811, married James Thomas (brother of Pleasant Thomas)
4. Barbara, born 1818, married Ransom Henry Rupe
5. Reuben, born 1821-22, married Barbara Ellen Maze
I cannot find Dewalt and Catherine's marriage in the Jacobs Lutheran Church records. If anyone has any information, please contact me.
