I was looking through _The Collector's Book of Doll Clothes_ and, while it has great pictures of a wide assortment of dolls, it does note that few rag dolls survive. There are a few pictures of rag dolls, including a couple of Izannah Walker dolls from post-civil war and an 1878 ad for "London Rag Baby Dolls" that the ad notes "can be thrown or knocked around without damaging them in the least. These latter dolls were muslin covered wax faces which to me would sustain damage if knocked about but every bit of advertising is the absolute truth, right!

Most of the dolls shown in the book through the end of the nineteenth century are wooden, china, bisque, wax, or composition (probably paper maiche) and a few rubber ones.
The greatest information on cloth dolls used in the general population will probably need to come from chance notations in diaries.
