What do the sources give for the date of births for the Josephs?
Born 1720, 1723 or 1732?? Has someone switched some digits?
Ingalls-355 originally was born in 1720. A bit later a different member changed his birth to 1723 and gave him a wife and mother. The original member intends him to be the son of -356 so that seems OK.
-1251 has a different birth date 1732. Is he the same person? Perhaps you could ask the profile manager who it is meant to be. -1251 didn't have parents until you added them. Is 1732 a typo for 1723 or is it a different person? If it is a different person, who actually married Sarah Abbott?
-356 (not -355) is married to his own mother and that should be removed, as it contradicts the gravestone saying she was a widower as reported in that book page.
