@Butrflynet,
Yeah, but if I stick to the truth I have less chance of forgetting what nonsensical word I chose, which I guess is the point, as was pointed out re 'secret question'.
Really I'm more interested in what a maiden name is, legally. There doesn't seem to be a lot of agreement in the various posts - the birth certificate is interesting, do they really change it if you get adopted? I'm not sure my mother was legally adopted anyway, or are you adopted by default if your mother marries? And what if it's all in a post war refugee camp in middle Europe?
