I think I am connected to your Belmont County Bigleys. My 3x great grandmother was Margaret Bigley b. 1812 Belmont County married Joseph B. Parks. Also my 3x great aunt Mary E. Ayers married Hamilton W. Bigly son of John Bigley (b. 1806) and Nancy Reed or Belmont County. Hamilton is living with Margaret and Joseph in 1870 which makes me think that John was Margaret's brother.
Does this sound remotely connected to anything on your family? Thanks
