Well, we can always assume that any family naming oddities could come from a family that has roots outside of any given nation but has been living there for a time. And since the British have a love hate relationship with the French, she probably could have a foreigner parent that chose to give her a foreign sounding name.

It's not that hard to come up with a number of explanations for this, I think.

A person living in the UK giving someone a French given name sounds like a bad idea all-around. Both in terms of social health and physical health.
