If you give me a couple names on your up line of Emler's I might be able to connect you to something I have that goes back to Imler/Emler. The name has been modified several times from Emler/Imler/Immler/Imbler/Embler.
I have Emler's in Ohio,Iowa,Tennessee,North Carolina,Oklahoma,Kansas,Wisconsin,Texas,and Pennsylvania but no Indiana Emler's
You can e-mail me direct at
Bedfordbarleys@aol.com and we will try to connect you with someone in my database
