Gosh some of those look very old indeed. I would speak to a textile convervator about cleaning them, I bet their appearance could be improved with the right treatment.
That last one looks like ayrshire embroidery. I have an early christening robe with that style of embroidery ca 1840s.
Thank you for the comments I have some other things I found with the bonnets I'm guessing age range from mid 1800's to late 1800's
oh wow! you must check out the V&A collections online, they have some dolls done up with original period costume like this. Is the scale of the red coat suggesting child or doll?
The red piece is actually a newborns shirt I also have a dark blue one as well as several little shirts in a white satiny fabric.
It seems so sad that these once treasured items were just tossed out in the trash.....but lovely that you were able to rescue them! Hope you have luck at cleaning and preserving them.
