Yes, was a name from a relative on my father’s side. However, it also happened to be the name of the county in California I was born in. So there was that. In any case I thought it was kind of cool. so when coming up with a computer login, I used first initial + middle name instead of last name. This was back in high school in the 1970s, and yes, there were actually computers and login names even then! And that username lives on to this day (hint: see my forum name, 45 years later)
Yes. In India, your middle is your fathers first name. For women, after marriage, your middle name becomes your husband’s first name. That tradition may be changing or may have already changed, but for past generations holds true.
