You're right, Dennis, it could have been another reason. I was just throwing that out there as a possibility. Even if they were younger than 65, they could have been using it to apply for their first Social Security number in preparation for the time they would eventually be eligible for benefits. Though Social Security was put into law in 1935, it may have taken a while for some people to actually make application to become part of the system. My Granddaddy Gilchrist applied for his in 1937 when he was age 44. Your ancestor may have needed the notarized copy as documentation for a legal case, such as proving they were related to someone as an heir, but that doesn't seem likely since you said the page doesn't show the parents. You definitely have an interesting document and it is fun to speculate. Hopefully, someday, you'll solve the mystery. When you do, I hope you'll let us know!
