I have a good source for the Mennonite families in Lincoln County, such as Isaac Wismer and his wife Anna Moyer in the book "Samuel Fry the Weaver and Mennonites of the Twenty" by Barbara F. Coffman. It's volume no. 8 (1982) in a series published by The Pennsylvania German Folklore Society of Ontario. The great thing about this book is that it has 15 family trees in 19 charts for the early Pennsylvania German families that settled along Twenty Mile Creek in Lincoln County, Ontario. The weak point is that Barbara Coffman didn't annotate her book that well, so I'm not sure what her sources were. I suspect that she used information in the A.J. Fretz books, such as "Brief History of John Wismer and Complete Genealogical Family Register" (1893) and the "Genealogical Record of the descendants of Christian and Hans Meyer and other pioneers" (1896)for some of the descendents charts
A word about name, The Twenty: the surveyors obviously weren't too creative and named the creeks or small streams along the shoreline of Lake Ontario by their distance from the Niagara River. Hence, the Sixteen, the Twenty, the Forty... The Mennonite settlement at The Twenty, beginning in 1786, was the first Mennonite settlement in Canada. There is now a museum honoring these pioneers, the Jordan Museum of the Twenty.
My gggrandfather Jacob Fry was a brother to Samuel Fry the Weaver, the central character in the book - so this book has helped me greatly in my family history research.
On to details on Isaac and Anna. There may be some confusion as Isaacs and Abrahams alternate for a couple of generations.
Isaac Gross Wismer was the son of Abraham Wismer (b. 13 Aug 1803, d. 23 Mar. 1895) and Susanna Grobb (b. 4 Feb 1809, d. 24 Dec. 1883). Abraham and Susanna were married on 29 Dec. 1826.
Abraham Wismer (1803-1895) was the son of Isaac Wismer (1782-1848) and Anna High.
Isaac Wismer was the son of Abraham Wismer and Veronica (Fronica) Meyer. Isaac came to Lincoln Co. in 1800, probably with his uncle John High the pioneer. Isaac's homestead was lot 22 Broken front of Concession I in Louth Twp. Moved to Jordan and had a store with Abraham Martin.

Elizabeth Fretz was the daughter of John Fretz (no indication which John...)
Anna Moyer (wife of Isaac Grobb Wismer) was the daughter of Rev. Jacob B. Moyer (b. 6 Oct. 1792, d. 17 Feb. 1831) and Anna Albright (b. 8 Apr. 1792, d. 29 dec. 1856)
Rev. Jacob B. Moyer was the son of Rev. Bishop Jacob Moyer (b. 24 Nov. 1767, d. 5 June 1833) and Magdelena Bechtel (b. 24 Mar. 1773, d. 1816) Jacob and Magdelena came to Canada in 1799
Veronica Meyer was a sister of Bishop Jacob Moyer ( and therefore a great aunt of Anna Moyer, wife of Isaac Grobb Wismer)
BTW, the 15 family trees are for CULP, FRETZ, FRY, FUNK, GROBB, HIGH (HOCH), HIPPLE, HOUSSER, HUNSBERGER, KRATZ, MEYER & MOYER, NASH, RITTENHOUSE, WISMER.
I hope that this helpful to you.
An interesting side note: A group of my cousins are going to Lincoln County to do a family heritage tour in the summer of 2001. We're going to be staying at, the Martin House, a Bed and Breakfast in the home formerly owned by Abraham Martin (the merchant / partner of the grandfather Isaac Wismer mentioned above)
