Name dillemma

Moshi • Mummy of Sage Autumn 😍

ok so, my two favourite names in the world I can no longer use. Oscar was to be our boys name, and Harper was to be our girls name. However 2 weeks after my miscarriage in May, my "best friends" used the name Harper for their baby, after previously hearing me say "if I have a girl she'll be called Harper" and saying they disliked the name. After my MC, I decided my baby would have been a boy and called him Oscar, because it was easier to mourn by giving him an identity. Does anyone have any suggestions for new names that are equally cute but not so common there's going to be loads of them around?
