I can help.From Charles Duesler's book, Emeline A. Duesler, b. 01 Jan 1851, apparently moved to Brimfield IN about 1866 where brother John had located.She married Cris Planck on 15 Mar 1870.They first lived in Rome City, then in Michigan, then at Elkhart, IN.There were six children--Edward, Robert, Roy, Lauri, Hatti, and Clara.
Emeline was the 11th of 13 children of Jacob Duesler, b. 19 Mar 1809, and Nancy Halladay, b. 20 Mar 1812.
Jacob was the 8th of 11 children of John Jacob Duesler and Mathalain Seitz.John Jacob was the son of Andreas, one of the two imigrant brothers.
Charles' book has much more info on siblings, etc.Send me an email, and I can send info by snail mail.
