Anything ending in -lyn/-lynn, -syn/-son, -tyn/ton, -dyn/-den/-dan, or -lee/-ley/-leigh.
Nevaeh is the first to come to my mind.
The Aden names. Syllable mash-ups like Braylee and Kinsleigh (blergh). Al- names like Alison and Alexis (though never Alice!) and Mac- names like Mackenzie and Makayla and McKenna. -son names like Carson and Madison and Grayson and Hudson. Em- names like Emma, Emily, Emery, Emerson, etc. El- names like Ella, Ellie, Isabelle, etc. Lincoln, Regan, Kennedy, and all the other presidential names. Prissy 'spiritual' names like Destiny, Trinity, Faith, and Genesis. Trashy place names like Brooklyn, London, and Paris (still hoping that last one gets reclaimed for boys!). Try-too-hard names like Maverick and Riker. Every kree8tiv misspelling under the sun.
OH, and boys' names on girls. God, will I be happy to see that trend die, though I feel really sorry for the poor women who'll go through life named Elliot and Rory and James.
Harper (big time)
Cohen (I feel so bad for the kids who'll have to wait to turn 18 before they can change their name to something not awful)
I can also see Ad- names like Adelaide, Adeline, and Adele being as tired in 50 years as Madison and Mackenzie are now. I think the middle name Wren will be the new Grace (which was the new Rose). I think we'll also see a lot more occupational names for both genders.
