Which name would you prefer for a little girl?

Kendall Ann Martin or Trinity Ann Martin? I don't like that Kendall doesn't have any pretty nicknames, and Trinity could be turned into Trini for a nickname. I really want a name that can have a nickname, I'm not sure why I just do! I love both of the names though, and wondering which one you would prefer for a girl? And the middle name Ann is non-negotiable. I don't care if it's "filler" or common- it is for my sister and that is what's really important. So... Kendall Ann or Trinity Ann?
