If that doll is representative of the rest, they're not Civil-war era. The tag on the doll more than makes that apparent. ^^ It's machined, and dolls previous to 1910 were completely handmade without tags and such. The fabrics and textiles scream to me 1930, which searching for information on 'Kimcraft,' dolls, seems to be about the time the company was active. Looking at her face, I think she's had a repaint at one time. I see what looks to be composition crazing, and the paint goes 'into' the crazing, which is pretty indicative of a repaint. There's very little information on these dolls, and they're not at all in my study, but she's no older than 1920, and from what examples I can find, this doll has had some work done to her paint and she may have had a wig. Her molded hair doesn't look original to me, but that's just my guesses.
