From what you sa it is likely a composition doll made somewhere between 1910 and 1920 !! Composition material is basically sawdust and glue with a few other ingredients added,, cornstarch ect !! They were the least expensive dolls to make !! None of the mfrs ever glued clothes on that I have heard of !! Look at the glued on parts and see if the glue has a yellow tint !! That would indicate an older type of glue mostly made of animal hide !! More modern glues are clear when dry !!
No way to know who made the doll without a name !! They rarely had one !! They were not expensive and many people bought them and made the dresses and sold them !! I remember similar dolls from when I was young !! I am 70 years old !! So the doll may be an older one but may have been dressed later !! These were just to sit around the bedroom and look nice,, not for a child to play with !! Was your aunt a single lady ?? I could imagine her having this doll from looking at the clothing style !!
