That's interesting ... about the Jewish naming system. Roughly the same thing happens (or certainly used to) among the Luo people around Lake Victoria in Kenya, where I lived. Most, not all, Luo names start with an A for females, O for males ... so my 3 daughters were given Luo names beginning with A ... (Atieno, Adhiambo and Achieng') and my son Obong'o !!! Not many white children can claim Luo names !!
BUT, and this is where the system gets a bit difficult to follow, a Luo child is often named after a notable local person who died soon before their birth ... so you can sometimes get men with apparently (because of their initial letter) female names, and vice versa !!
Nowadays, children are often given western names, so I know a Luo boy called Evans Owuor !!
Anyway, this is getting away from the thread ... but I found it very interesting at the time when I lived there ... and it does, like the Jewish system, carry on the name of someone who has died.
