I have a Barnwell Preston BEARD b.c. 1832. I have him listed on the 1860 SC Census, Colleton Co.
I haven't had much luck connecting him to any parents or other family member other than his own wife and children until recently when I came across a ship passenger list from Panama to San Fran, CA 1852... the passenger next to B.P. BEARD was W.B. PRESTON. I'm hoping there is a connection somehow.
"Barney" would have been abt. 21 when he ventured out west during the 'Gold Rush Days'. But he is in SC in 1860, so he didn't stay long.
I was curious to see your family name of BRADWELL.
