Jake, Don't know if this will help at all but I have a Jacobs who immigrated to Milwaukee from Losheim. Her name was Maria Jacobs, born 1820 and married to Johann Schuler (parts of the family changed the spelling to Shuler after settling in Janesville. Anyway, I know that Maria had many siblings although I don't know the names. She was the daughter of Nikolaus Jacobs and Barbara Minninger. Let me know if any of this sounds familiar. I should say that they came to the States in 1852 (direct to Milwaukee). Kind regards, Dave
