Avner, Frumit, Bashi, Binyomin, and Yonason to name a few.
Avner – The father of the candle (or alternativel, the father of Ner), Frumit – the religious one, Binyomin (the son of the right (hand), and Yonason – G-d gave. Bashi probably IS a derivative of Batya.
I don’t know for certain, but perhaps Dovid comes from “Dod” or loved one (as in Ani l’dodi.) It is spelled exactly the same in Hebrew.
Well I know an Ester is a chemical compound derived by reacting an oxoacid with a hydroxyl compound such as an alcohol or phenol. Maybe she smelled nice. Mordechai I don’t know, is it some kind of slang? Like, “more da chai mon” – Judeo-Jamaican for “more life”.
