Yes, I agree. I believe it is my GGrandma Gladys in that Census. It surely fits everything I know. I sometimes wonder who amazing it is that we can piece together so much of the past with such little info. :-)
I hadn't thought to ask Social Security. I will try that. I was thinking.... what is the best plan to get the birth certificate. Try one state and request it? Then if no luck, try the other! That was my plan.
