The Farrow you're looking for is John Farrow 1826-1892 son of Isaac and Ann Rankin Farrow.
http://www.geni.com/people/John-Farrow/6000000015325128383 I haven't seen any proof he married an Argenbright or a Susan, but it's widely reported he married either Susan Jane Argenbright or Ann Argenbright. His son's marriage license lists "Ann" as his (the son's) mother, and John Farrow married Elizabeth Wash after the death of his first wife. They are listed together in the 1870 and 1880 censuses.
