i would use it anyway. but id have to deal with some angry/bitter issues 1st because you dont do that to family. to a friend, maybe, but not family.
im having a weird but similar thing happen. everyone i know that is NOT pregnant yet, some not even in a relationship, is claiming names left and right. the conversations are going like this.
them: "do you have a name picked yet?"
me: "no not quite yet, i want to find out the gender first and make it easier to brainstorm."
them: "ok well when i have a boy im using ____ and when i have a girl it will be ___."
me: "ok, nice names"
them: "yah well dont use them"
now granted they arent names on my short or even long list. but i dont see why my neighbor or whoever can all of a sudden claim names that im not "allowed to use." like i said, you dont do that to family or best friends, but names arent copyrighted.
