Seeking info on my GGF Peter Dyckman who was born c 1809 and was in Harris Co, Tx in 1850.(He arrived in TX in 1839.) He married Delina Dunmam dau of Joseph Dunman on 12/21/1840 in Harris Co., TX. He had a brother named Herman who was killed and robbed in San Antonio in 1839. 1850 census shows Peter was born in Germany and on 1900 census my GM says he was born in PA. Any info on his family would be greatly appreciated.
