I like Haven for a boy; I've had it in a combo forever.
As a girl's name, it doesn't really 'go' with Lillian.
However, I don't see how your niece's name is relevant at all. If they were family members who would spend a lot of time together, that might be a consideration, but they're not... Your sister's friend shouldn't have to consider your niece.
