I see similar situations on here a could of times lately and figured I'd post as there doesn't seem to be any that's exact to this and it often borderlines on U or not on these threads so just wondering.
My son is Frederick Jonathan. He goes by Freddie and is 5.
My niece is naming her little boy (due in 3 days) Freddy John.
A lot of our family is still very close and see each other once a month. AIBU to think this is a bit copy cat? No family names either.
