Miniature figures (paper mache)

This is one of my favorite purchases because I don't really know much about them..there are around 70 miniature figures only 1" tall and seem to be made from paper mache..there are some religious figures, wedding figures and some playing instruments..they are so tiny yet very detailed..the way they are dressed looks to be from the late 1800's to the early 1900's..could they have been used in a old model train set ? If you know anything about them, please let me know! Thank you
