Ellen Asay was my second great-grandmother. I have her date of birth as March 23, 1853. She was born in Illinois. She married Aaron Winfield Leeds in Rock Island County, Illinois on August 27, 1871. They are found in Cherokee County, Iowa in the 1900 census. She died September 26, 1927 in Cherokee and is buried there in Oak Hill Cemetery.
I would be thrilled to obtain copies of the tin types you mentioned in your post and share additional information.
