“Delayed Birth Certificate
If you were born in the United States and cannot present primary evidence of U.S. citizenship because your U.S. Birth Certificate was not filed within the first year of your birth, you may submit a Delayed U.S. Birth Certificate. A Delayed U.S. Birth Certificate filed more than one year after your birth may be acceptable if:
It lists the documentation used to create it (preferably early public records) and It is signed by the birth attendant or lists an affidavit signed by the parents
If your Delayed U.S. Birth Certificate does not include these items, it should be submitted together with Early Public Records.”
I had ruled out the delayed birth certificate..but it does say affidavit signed by the parent((S)). That would mean both parent’s signature. You may be on to something....1971 visit????
My father was born at home in 1912. He lived to be 95 and never had a birth certificate until he was 65 and needed one for SS. Both his parents were deceased so he had an Aunt who filled out an affidavit swearing to all the information to the best of her knowledge and then he was issued a "Delayed Birth Certificate."
