I realize it has been 13 years since you wrote your last post. My name is Phyllis Krupka and your Great Grandmother Florence Eschmann was my Great Aunt. Her maiden name was Ossman. Her brother Fred was my grandfather. Their father was also Frederick. Frederick Ossman Sr. was married to Amelia Pressler. They had three children, Florence, Frederick and a third child who died in an automobile accident when she was a teenager. Your grandfather, John also had a third brother whose name I cannot remember, who died shortly after WWII.
I hope this helps a little. I would love to hear from you. I met your mother and aunt when I was a little girl.
