My birth ln is a form of
David. I didn't mind it as a ln, ditched it when I married because I could get better initials that way (!), and used
David as my son's mn without hesitation. Where I live, I haven't seen a young
David for a very long time. This is a pity: I find it attractive, and
Dave is fine as a nn. My uncle by marriage,
David, was called
Davy by his wife and I didn't like that at all.
