I love Peter. Such a lovely, simple name, James is ok. Not keen on the others and i really do not like Lewis and Tyler. Jane and Rebecca are lovely. Do not like the others, I especially do not like Kara.
Alexander, James, Isabella and Rebecca are all ab fab names! Evie and Harry are VERY popular at the mo; Tyler sounds American; not a fan of Lewis, Peter or Kara, and Smeg ..sorry Megan I really don't like at all! Hey ho!
Boys Alexander -- Nice Harry -- Nice James -- ok Lewis -- dislike -- prefer Louis Peter -- Love Tyler -- Dislike a lot
Girls Evie -- way too popular Isabella -- way too popular. Half of the girls on the planet bear this name Jane -- Lovely and unusual Kara -- meh Megan -- dislike; 'egg' sound in the middle kills it for me Rebecca -- lovely
Nothing really jumps out at me from your boys' list except Peter, but Alexander and Harry (while very popular) are nice too.
Jane and Rebecca get my vote from your girls' list.
