Samantha was always my favorite, followed by Felicity, then Molly.
Samantha was the first doll I got, and then I got Addie b/c she had the cutest pink dress ever. I absolutely loveeeeed these dolls. My best friend had ALL of the dolls and every accessory that was available at that time. She was somewhat spoiled you might guess.
But we still had so much fun with these dolls. I liked the books though even more than the dolls.
Reading this thread makes me want to go read my American Girl books again!!
