French Provincial Style Furniture

I was given these 3 pieces of furniture but i do not have much information on them. The woman who gave me the furniture is a registered nurse and she once cared for an elderly couple that gifted her the pieces. The three pieces of furniture came from their home. Both have now passed therefore I am unable to obtain any information. I'm interested in knowing the history of these pieces, the time period especially. All 3 pieces are lighter than expected in weight, the drawers include dovetail joints and also two out of the three pieces have casters. Each piece also includes a glass top as you'll notice in some of the pictures. There are absolutely no labels, stamps, carvings, handwriting, etc. on any of the pieces.
