Research question related to 0:

In 1961, what were the rules & processes whereby a young child (about 2 to 10 years old) would get added onto an adult’s passport?

What supporting documents were needed?

Affidavits, court orders, etc; what was used?

No idea as to the rules and regulations at that time. To research, for fair and balanced with no pro-BO’B propaganda, it might be best to research Ted Cruz and how his mother was able to get him into this nation. The two different years are not that far apart. Wish you the best in digging.

I remember when we went to the local courthouse to get an endorsement for my two-year-old baby brother to be put onto a page in my mother's passport. She just presented his birth certificate from the local hospital and a picture ID of my brother with her American passport. I don't know about a fee, but I presume there was one.

A child would need his own passport at age 16. From 2 until 16, a parent (generally) needs to present citizenship evidence, photocopy of ID, photo, and fees.
