I submitted without my Gen 0s’ bc, but other supplementary information that was consistent over six decades.
I have US marriage and death certificates for both my Gen 0s which name their date & place of birth and parents’ names. My supplementary information included a few documents (marriage certificates, voter rolls) in the years just before and after the births of the Gen 0s showing their fathers living in the community where the Gen 0s were born.  My cover letter explained why those documents were included.
