In French and most languages names don't change unless it is a word that exists in that language therefore the name Kaitlyn would remain the same just with a French accent
For example, if I say “une table” – the gender is feminine, and the number is singular. Both are show by the French article “une”in this example, however your French teacher may have withhold this information during the test if you had to memorize a list of French words!
1. Vieux, nouveau
2. Belle , blanche
3. intéressants
Good luck
