Simon's birthdate is said to be 11 Jan 1809, but that doesn't even come close to his ages in the 1850/60/70 censuses.

Joseph is probably the result of enumerator error in the 1850 census, where he should have been enumerated as Josephine.

George Wilson FOUGHT is said to be the son of Reuben & Angeline (WISSINGER) UPDEGRAFF, the wife of which couple is our subject's sister-in-law, but all evidence points to George being a son of our subject.  George is living with our subject in the 1860, 1870, and 1880 censuses, and he is surnamed as our subject, not in any form of UPDEGRAFF.  While Reuben UPDEGRAFF did die in the 1860s leaving his wife a widow in 1870, he was alive for the 1860 census, and George was not living in Reuben's household in 1860, which surely he would have been as a four-year-old child.  The only child in Reuben's household in 1860 was his son, Vanlean UPDEGRAFF (b. 1854), and this son is living with Reuben's widow in the 1870 Census.  In the 1880 census of the household of widow Sarah (WISSINGER) FOUGHT, George is labeled as her "son," not as her "nephew" or "step-son."  Also in the 1880 census, George's father's birthplace is given as "PA" and his mother's as "MD."  Those are the birthplaces of Simon & Sarah, not of Reuben & Angeline, who were both born in OH.

Simon & Sarah were married in 1839 in Franklin Co., so we would expect Simon to appear in the 1840 census of Franklin Co. as head-of-household, but he does not.  Simon & Sarah have to be living with someone.  The only FOUGHT in Franklin Co., OH, is Simeon FOUGHT, who is the right age to be Simon's uncle (Simon's father died in 1837).  Is Simeon FOUGHT their uncle and are they living with him in 1840?

Simeon appears to be a widower; the elderly woman is likely his mother or mother-in-law.  There is room for Simon, Sarah, and Cathrine in the household.

Has the enumerator erred?  Is "Joseph" actually "Josephine"?  If not, where is Josephine?

This census-taker made a mistake with George's middle initial, and he appears to have made one with Francis's, too.  "Francis D." has to be "Francis C.," who has to be "Charles F."  If George were Reuben & Angeline's son, he should have been listed after Francis and should have been labeled "nephew" or, if legally adopted, "step-son," and his parents should have both been born in Ohio, not PA and MD.  I am thoroughly convinced that George is the son of Simon & Sarah, not Reuben & Angeline.
