I know that some of you may not be Christian and I am not trying to convert anyone, but I recently came across a new company called Dolls from Heaven. They make dolls based on important Christian figures. My mom recently bought St. Therese and the quality is very good. They are the same size as American Girl dolls and can even wear each others clothes (my sister bought a sailor suit from Dolls from Heaven to put on her AG Logan doll and it fit perfectly).
Another doll company that someone might be interested in is A Life in Faith. The company has been out of business for a few years, but you can still get the dolls on Ebay. They are based off of characters from the Elsie Dinsmore series, which is about a Christian girl growing up in the south during the mid 1800's. I have an Elsie doll and she is really nice quality and is the same size as an America Girl but with a hard body rather than a soft body. The clothes are really nice (I would have to say that the quality is better than American Girls). I also really like Elsie's curls.
