I've never been quite sure how to address conflicting birthdates in original sources that contain primary information, specifically, the great number of WW1 and WW2 draft cards that do not contain matching birthdates. I am aware of the reasons why someone may purposely change the date, but the numbers of men I have seems very large. I have many more that do not match than those that do. These dates are sometimes different then the various census records for that person.
I know that the further back in time we go, birthdates were less important and less known. But this presents a problem when I'd like to source a birthdate. I do always check the census to see which one is more likely to be accurate, and in some cases that helps, but when those dates vary widely I am simply at a loss. Do I source each WW1 and WW2 doc, with an "or" caveat? Do I cite a range of dates between those two documents and the census?
And happy 4th of July!
