I am looking for information on a David Caldwell [b.] 1804 in Pennsylvania. I know the family or at least David moved to Ohio and had children there before moving to Indiana. I know there has to be someone, somewhere, looking for a brother or sister of my David or has found them already. His children had names of Robert, John, Joseph, James, Samuel, David, Elizabeth, Prudence and possibly Hugh. These are relatively common names with the exception of Prudence and Hugh I know, but I have no info other than that. I think they were related to Boyd's, Byers or Myers. Can anyone help me?
