I have been studying the census on William Bean closely. What I have on the 1850 census gives his age as 56 This census was taken 2 Sept 1850.I don't have the 1860 census, but the 1870 gives his age as 75. This census was taken 22 July 1870. I have come to the conclusion that he was born between 22 July and 2 Sept 1794. THe 1850 census gives Hetta's age as 32 and the 1870 census gives her age as 53 which is correct. I tend to put my faith in these two census rather than in his tomestone. What do you think.
