I just reviewed the 1850 Census again and found that Abraham Neff and family were listed in the 1850 U.S. Federal Census Ross Co, OH on Page 237; Fam 362; Rec 369. It listed:
Abraham Neff 33 MOH Mary A Neff 32 FPA
According to this, Abraham was born in OH and not PA.
Although Abraham did not fit any of the children age categories for Leonard Neff in 1830 census, it is very close.Can anyone check to see what Township the above listing for Abraham is recorded?If it is Springfield Twp., this could be the connection.
