My aunt had found a certified copy of my grandfather's birth certificate in my grandmother's records. It was old. Not sure if it was an original from 1911 but it was old. I wasn't sure if it would be accepted but I sent it to Erie County for their authorization. They sent it on to NY State for an apostille because NY State called today for some extra information – apparently I transposed a digit on my credit card number – so that means both Erie County and NY would accept it. Great!
