It's possible. I added a Julius Ernst as a brother of my great-great grandfather Josef Ernst, because he's listed as a brother in a document my maternal grandfather's sister Maria wrote. Maybe Julius was a middle name. Most of the names she listed, you have. However there were a couple differences. I believe you listed a Georg, where she didn't. When I get home, I could make a copy of the page Julius Ernst is listed on, and email it to you.
