I am not a fan of shortened forms of names unless they are nicknames. I feel that way people have more options when it comes to what they prefer to be called. I also like using my full name (Gillian) for professional purposes, whereas my family and close friends call me by a nickname (Jill). It also made my life a lot easier in school. Because my full name is so close to Gilligan and Gilligan's Island was still on in re-runs when I was little, I was teased A LOT as a kid. After dealing with it for a couple years, my parents alerted the school that I went by Jill at home and suddenly the teasing stopped! My nickname saved me from quite a bit of trouble. Now I embrace my full name, but as I said, my close friends and family still call me Jill. I always thought Rory was a full name and it wasn't until I was substitute teaching this year that I met a girl in kindergarten named Aurora who went by Rory. I also know a boy named Ruairi, pronounced pretty much the same way, but is a more traditional Irish full name (they Americanized the pronunciation, even though the mom is from Ireland). The whole nickname Rory is a fairly new idea I think. I had always thought (until this year) it was a full name.
