I have a problem... I have two differant birthdates for my great grandfather--William A. Whisenhunt or "Bill", as he was called. His death certificate gave his d.o.b. as 6-25-91 (1891). The informant was "Records from C. S. G. Hospital". Now, I have a draft card that William (himself) filled out and it says his d.o.b. was 23 June 1892. The 1900 census also reports June 1892. His headstone only has "1891" on it. Which birthdate do I use? I'm inclined to use the earlier records---esp. since the military draft card was filled out by William himself, in 1917. Anyone have any feedback? A professional opinion, maybe? Help...
