The information I have is taken from the book by Rex O. Matthews, " Johann Jacob Klahr Of Grossbundenbach, Germany, And Berks County, Pennsylvania, And Some Of His Descendants ", printed by Masthof Press, Morgantown Pennsylvania.
The First Generation
Johan Jacob Klahr, b. ca1705, Altersweil or Allersweil, Switzerland, a son of Casper Klahr; m. May 30, 1730, Wiessbach, Germany, to Catharina Baumgarten, b. ca1710, dau. of Michael Baumgarten, also Swiss. Jacob and Catharina and presumably all five of their children emigrated to Pennsylvania in 1752, debarking at Philadelphia on September 26. From there they proceeded to newly formed Berks County where Catharina's brother Valentine lived. Three and a half years laterJacob, the interval indicating that he may have had to work and save his money in order to do so, purchased sixty-nine -plus acres of hilly land in remote Tulpehocken Township that only a few years earlier had belonged to the Penn family. As isolated as the land was, the soil was deep and fertile when cleared and there were other amenities, such as freedom from serfdom; friendly, helpful German-speaking neighbors; and a log church called Zion's or Blue Mountain. I will be posting more information found in the book in the next few days.
