Why does Rory get called Rory, Her name is Lorelai Leigh Gilmore. I know its been sagte its a nickname but normally they are shortened versions of ur name. Ive always wondered?

Rory is just a nickname for Lorelai. Sometimes shortened versions of names don't always make sense... like Chuck from Charles, Hank from Henry, Peggy from Margaret, Libby from Elizabeth, Dick from Richard, etc etc. That's my assumption at least.

Again it's due to the confusion factor of having 2 lorelai's but I do think that Du can get from Lorelai to Rory... here is my logic:
Lorelai can be shortened to Lora oder Lor (like Chris uses in season 7) and Lor is like Ror and everyone always adds a y on the end of nicknames. oder maybe it is just backward logic as not much in the lives of Lorelai and Rory makes complete sence! Hope that Du like my answer

I have thought about it too. I think that it would be confusing to have to Lorelais. Rory kind of is a shorten version of Lorelai in my opinion. I like it.

It kind of is a shortened version....lORlei...rORy...im not sure though....But I think its a pretty name :)

Yes, I think this has crossed every fan's mind. I've thought of it as a chain reaction too. Take Lorelai, shorten it to Lorrie (the Mehr traditional spelling), then for some reason substitute an "R" in there for the "L" and get "Rorrie" except spelled "Rory". That's my thought process at least.

The name rory is just the shortened version of lorelai, and not all nick-names make the best sense

In real life Edward Herrmann has a daughter named Rory, I wonder if there's some connection there???

Gilmore is an Scotch Irish surname, and Rory is a Scoth Irish girls name. With the Gilmore's known tendancy of marrying their own (Grandma Laurelai, aka "Trix", married her cousin) and using family names (3 generations of Laurelai's in the show), it seems possible that Rory is also a family nickname.
