Name taken

My husband and I picked out a name for a girl and a name for a boy long before we got married and started thinking of ttc. Now we are pregnant and still love both names. Addison for a girl and James for a boy. Really good friends just had a baby last week (we are only 7weeks) and they named her Addison. Do we need a new girl name or can we still use it without it sermon like we just took theirs?
