Hi, I'm curious about how I should classify my personal knowledge of another person's full name, maiden name, and birthday. Let's say my mother, for example. I obviously was not present at her birth, but I have celebrated her birthday with her every year that I can recall. Does that give me primary knowledge of the day, but not the year? Or would my knowledge be considered entirely secondary information?
I also wasn't alive when my mother still used her maiden name, though I know what it is. Could this even be considered personal knowledge? Or would it be considered something I learned in an interview? I assume it would be primary information if it were the interview. If it were considered personal knowledge, would it be secondary information?
Finally, if I know someone's full name -- first, middle, last -- but don't routinely call them by the whole thing and have never seen a vital record proving that that is, in fact, their legal name, can I consider my personal knowledge of their name to be primary information?
