Unfortunately I can't help you with the Ish family and this information may not be helpful at all to you but I felt I should post it just in case.
I'm not a descendant of either the Schrader or Ish families but my late mother's family knew the Schraders in Hardin County, OH many, many years ago.How do I know this?Well because in the old, old photos left behind when my late mother passed away are three photos of Schraders.One is of Charles and Lizzie Schrader, it is labeled "Lizzie Schrader and husband", another is of Lizzie Schrader's sister Marie Yost, and yet another is labeled "Lizzie Schrader's girl", I don't know which daughter this one refers to as I just found out today there were two daughters of Lizzie Schrader, namely Christena and Ruthella, and I only found out today that Lizzie Schrader was formerly a Yost and that her husband was named Charles Schrader.
The reason I started looking, simply put, is because for years I have looked at those photos and wondered who Lizzie Schrader and Marie Yost were.I don't remember what my mother said about them, if anything, and I was frankly curious so I started looking on the Internet for postings concerning these names.
My mother wasn't born in Kenton, OH but she lived not far from there, her grandmother (my great-grandmother) Elizabeth Bachmann Bower/Bowers came from Switzerland and married in Hardin County, OH in 1878, she and her husband lived in Kenton for a while.I'm thinking perhaps the Schraders and Bower families might have been just good friends, I saw some information today which indicated that some of the Yosts in Kenton came from Switzerland too.But somehow these photos were given to my late mother's family and so there was some connection, even if the families were just good friends.
Since you are a Schrader descendant you probably already know of or have the same photos I refer to but if you want to know anything else about this, please e-mail me email@example.com
