Help with my baby names please?

Out of the girls names I like Serena, Alanna and Daphne. They are pretty names for a girl. However I don't like the middle name Morgan as a middle name. Lillian is a good middle name as well as Rosanna. It all depends on what your last name is and it sounds with it. For the boys names I like Seth, Nathan and Trevor. Your boys names are not that bad, I like most of them except for Tyson and Youir. I don't know if that is a misspell or if you mistyped it. I also like the name Rhys. Unique.
