What's in a Name?

I assume this is because of my age, but when I talk to friends/family members who've read my book they often ask if the characters are people I know. No offence intended for anyone who does base characters on people they know, but I find this a bit offensive...I grew out of that in primary school. The names of the characters in Brown Leather Shoes (and the sequel currently under construction) all mean something that I think is appropriate for their character, or maybe just sound the way that I want them to, or connote something particular. Names of characters aren't something that I just choose randomly, but something that I give a lot of thought to. This is because the characters are really important to me, and I have a very specific idea of what they're like in my mind.

For example: the protagonist (or one of them) is called Andrew Isaac Arling. Andrew is Greek for 'courageous' or 'manly'; Isaac is Hebrew for 'he will laugh'; and Arling is a patronymic from Old French/Old German which combines the Germanic elements "erl", meaning 'warrior', and "wine", meaning 'friend'. His middle name will become clear when you read BLS (Brown Leather Shoes), but the others are self-explanatory. His name is one of the more obvious ones, because I liked the names and their meanings (both of which are important to me).

What about you? What do you think about character's names, either as a reader or a writer (or both)?
