Hmm, I like it. I can't really see how
Ian could be a nn for
Finnen, though. If there was another brother his name would be
Eamon or
Edmund, and if there was another sister her name would be
Aurelie or
Aurelia. Middle names-
Finnen Ewan,
Marion Ivy,
Rosalie Mabel.
Finnen is pronaunced "FINN-ehn", I think.
