My name is Katlyn,pronounced like regular old Katelyn.
I like it better than my mother's alternative,Marissa.....
Yeah,I am named after someone,sort of...My middle name is Jean (if you so much as utter one sylabul against it I WILL HUNT YOU DOWN AND GUT YOU LIKE A FISH!!!!!)(I had a grinch moment,lol) which is my great grandma's middle name.My mom and Grandma's middle names are both Lynn,so mom pretends that that's the reason for the Lyn in Katlyn.
I wouldn't change it,even if it's pronounciation gets magled.
