Best combination of names for last name Braychev?

The baby will be mixed raced with black dad and white mum, the father is from Brazil, the mum from Bulgaria, the baby will probably be born in Spain so probably will be Spanish citizen. It will take the mum last name which will be Braychev for boy and Braycheva for girl. For girl I am thinking about Natasha, Simona, Marina, Isabella, Bela, Nell, Anadyomena, Belen. For boy I think about Patrick, Simon, Simeon, Emanuel, Luciano, Martin, Alexander, Viggo. What do you think is the best combination for first and second name? Or you have other ideas?
