Searching for my cat’s siblings

This is totally random but I want to find my cat’s litter mates lol. I got her in Seattle, Washington at the university district Paws. I adopted her in September of 2013 and her birthday is 7/7/13. She is a tortie longhair but idk about her siblings. I know that her two of her siblings used to be named Duel and Duet (my kitty was named Tortie Girl😂) but don’t know the others or if they are still named that

Pic is of my kitty

Edit to change title
