Has anyone studied the genealogy of the Wissler/Wysler/Wisler families in Richard Warren Davis' book "Emigrants, Refugees and Prisoners, Vol. I"?He has some relationships which do not agree with Oby Bonawit's breakdown of the Wisler/Wissler/Whisler families in his book. For example, Davis has the Jacob Wisler, b. 25 Jul 1738, who married Catharine Gruber, as a son of Benedict Wissler, b. ca 1707, and grandson of Heinrich Wissler, b. 25 Jan 1657, and Barbara Grumbacher. Bonawit has this Jacob, b. 1738, as a son of Heinrich and Anna Wissler of Donegal Twp. Would appreciate any thoughts on this.
