In the Book of Strattons, Vol.1 pg.290, she has Josiah married to Sarah Adams. Maybe she died and he married the Mary.Or could Mary have been her middle name or nick name? William and John are both still living at home on the 1860 census. John being the age of 50 and William the age of 40.There is a Josiah Stratton (Son)maybe,according to the 1850 census, was living in Camden New Jersey and was an iron molder. But i found nothing after that.John died unmarried but if the John Stratton in Camden N.J. is him on the 1870 census, he was living with a woman.William (maybe him) is living in Burlington married to a Lady by the name of Sarah.Will try to find out more.
