My name is is Tarina and I also disliked it as a child, but love it now. It's pronounced Tah-ree-nuh. Mom said she heard it in a movie in the early 60's.
My name is Tarina I didn't like my name as a child because it was uncommon and people would mispronounce my name all the time. So to avoid having people say my name wrong I started just saying call me Trina which I dislike as well, but it was more to help people say my name than for me. But I'd rather use Trina than Katrina. My mom said she saw an actress in a movie in the 60's or 70's, not sure the movie's name but that's where she saw the name.
