I chose the name Marie, after our blessed lady, but also since my middle name is Anne, and my best friends at school were Anne, Marie and Ann-Marie
I gave my eldest daughter the middle name Anne (after my best friend, who was also DHs sister - she died in a car accident in '84) and my second daughter the middle name Mary (my mums middle name, and dh's middle name - all his siblings have Mary after our lady), and my new daughter the name Anna Maria after both of them

It was important to me to choose biblical names, though - Catryn (although spelt differently) is a saint, and Rebecca is in the bible, as is James and John (his middle name).
Sorry, I rambled
