I am researching the Kummerer/Commerer/Gumery/Cummer line both in Lancaster and Berks County in the 1700's. The Kaufman/Kaufmann line in Berks County in the 1800's. The Ohl family in Northampton County in the 18 and 1700's. The Richard line in Northampton in the 17 and 1800's. All moved to Stephenson County Illinois which is just south of Madison Wisc.
