A friend reminded me of this bit in Evelyn Waugh's The Loved One:

'I took Art at College as my second subject one semester. I'd have taken it as a first subject only Dad lost his money in religion so I had to learn a trade.'
'He lost his money in religion?'
'Yes, the Four Square Gospel. That's why I'm called Aimee, after Aimee Macpherson. Dad wanted to change the name after he lost his money. I wanted to change it too but it kinda stuck. Mother always kept forgetting what we'd changed it to and then she'd find a new one. Once you start changing a name, you see, there's no reason ever to stop. One always hears one that sounds better. Besides you see poor Mother was an alcoholic. But we always came back to Aimee between fancy names and in the end it was Aimee won through.'
