proof of birth date when naturalizing?

[tr888]

First, nice site, though the "captcha" during registration was the most difficult one I have ever encountered! I hope that captcha wasn't a harbinger of what lies ahead for me in the jure sanguinis application process

When a person came before the Immigration and Naturalization Service around 1938, what evidence of the petitioner's date of birth was required? Did the petitioner have to provide an Italian birth certificate to the INS? Ditto for the minor children listed on the petition.

Thanks
