I'm trying to determine the birthdates of my relatives who left Berks County, PA and were in Armstrong County in 1840 and 1850. John and Lydia Welder were in Red Bank in these census years and had at least six children--- Peter(born about 1834), William(born about 1836), Benjamin(born about 1838), Maria(born about 1840), John(born about 1842), and Adam(born about 1847). I'm also interested in exchanging information on this family with anyone out there. Thanx so much for your time and interest. Kerm in Berks County
