Who is the person that breaks down first names to determine their origin and meaning?

Question

What is this profession called?

Answer 1

Joseph Gilbert?

Just kidding but the article at the site below talks about the meaning of names and his name is one of the ones indicated as some sort of expert in the field. But I think that is for surnames. Given names are addessed at the 2nd site, but I still don't think there is a name for the profession except maybe linguist.

OK, I found the answer. on·o·mas·ti·cian


Onomastics (or onomatology) is the study of names. The word is derived from Greek ονομα (onoma) which means "name".

Questions onomasticians try to answer about given names include:

What they mean - their etymology or origin.
How they are used in various cultures.
Why some are chosen by parents more often than others.
