For those that is not aware of it - I just found it- you can check dates in the Social Security records. You will have to know something about the person - to be sure that you have the correct person - check it out: http://www.ancestry.com/ssdi/advanced.htm I found several that I knew one date - but didn't know the other date. also I knew - I had the correct person - by the name and place and the one date that I did have. Good hunting. Ruth
