Berks County Church Records p 107 has a Johann Friderich Stump christening. This kid was illegitmate son of Johann Fridrich Stump and Anna Ros. Schwabin. Child was born 5/24/1783 and christened 6/8/1783. Sponsors at christening were jacob Schwab and Catharina. I don't have other information on him or when he died. I presume there was a family connection between the sponsors and the mother. The book Pennsylvania German Marriages shows a marriage at Schwartzwald Reformed Church of Exeter Twp, Berks Co. PA. for Johannes Stump and Esther Klein of Bern on 11/28/1792. Marriage performed by Rev. John William Boos. Same marriage reported in the book Berks County Church Records of the 18th century for the Reformed church of Reading. Same date. I've got some other John Stumps, none with DODs, in Lebanon County and at Germantown, plus one in Somerset County PA.. Not to mention a couple who are just from "PA". Jan T
