Names Meaning "Angel"

Hi all! We just found out we are having a little girl and could not be more thrilled - or surprised! I thought for SURE I was having a boy. But anyway. :) We still have a loooong way to go on first names, but for her middle name, we want to do something to honor my aunt who passed away from colon cancer a few years ago. We were very close, and unfortunately, her first name (Patricia) sorta rhymes with my husband's last name and doesn't sound great together. But one of my most enduring memories of her was her love of angels. Would love to come up with some ideas for middle names that could reflect that.
