Family and baby names

So my boyfriend and I don't know the sex of the baby yet but we have a boy and girl name picked out.... every time part of his family hears the names we like they make comments like oh no please don't name the baby that, that's redneck, they are never going to find their name on anything, that's too old, etc.... I know its our baby and what we want to name it is all that matters but it does bother me. Anyone else experience this? My name is a common name but spelled very different and I could never find my name on anything but it never really made a difference to me..
