I've been collecting data on this Schlemp/Slemp line for several years and would very much like to compare information with any of you. I can send a Microsoft Word file to anyone who will contact me directly.
My line is:
Larry Cockerham John Cockerham - Hazel Parker Lura Cress - Robert Parker Ulysses Grant Cress - Martha Arnold John M. Cress Jr. - Melvina Farris Samuel Cress Sr. - Sarah Shupe Peter Shupe - Mary Polly Slemp Johann Friderich Schlemp Sr. - Mary Metz Gearge Simon Schlemp - Anna Margarethe Zangmeister
The Zangmeister line has been traced back to ca 1400 Bavaria and is/was shown on Ed Weaver's Zangmeister Genealogy Page in 2001. He claimed the data came from Dieter and Joan Zangmeister in Germany.
