Sapphire, thank you! Those panels are very similar in style, paticularly the lily pads.
Mart, this painting was from my Grandmother in Wisconsin. There are a lot of marsh areas with these water birds where she lived. However, her mother and father came here from England, and my Grandfather from Scotland. Both families brought some interesting things with them. So, I do not know if this old oil is even from the U.S.
Just once, some time ago, I saw a VERY similar painting on Google Images. The same bold, heavy, dark appearance. I book-marked that and after a computer crash, lost that one.
