The purpose of the Grindle DNA project is to find where relationships may exist between various family lines, thus expanding genealogical research through Y-DNA testing. A primary goal of the project is to reveal whether early Grindle families of Maine and New Hampshire; Grindle families of Pennsylvania; and/or Grindle families of Maryland, Virginia,and South Carolina, who immigrated to America during the years 1600-1800 are related. In addition, three Grindle men who served in the Revolutionary War in Pennsylvania – John Grindle, Jacob Grindle and Henry Grindle – are a focus of this project. Another goal is determining the countries of origin of all these immigrant lines. Therefore all MALES who HAVE the GRINDLE surname, or any variation thereof, are invited to join the project and take a Y-DNA test. If you are researching and wish to learn more about your Grindle ancestors please encourage an eligible MALE in your family line to participate. This project seeks to determine the genetic connections of all lines of the Grindle family surname worldwide by means of the Y-chromosome DNA test, thereby finding new cousins and family origins. Little is known, or written proof found, of the Grindle lines in Pennsylvania. Family lore and myths also abound. Some say they were of English heritage; others say Dutch, German or Swiss heritage. Early church records of Southwestern Pennsylvania - primarily German Lutheran or Reformed Lutheran - were written in German and subsequently translated to English. This would lead one to believe they may be of German descent. The three Grindle men who served in the Revolutionary War in Pennsylvania are believed to be either brothers, or father and sons. Grindle grave sites have been located in Mennonite cemeteries. One local history in Southwestern Pennsylvania states its area was originally settled by Brethren from Europe. There are known descendants of these Grindle lines but no evidence to confirm relationship. A firm brick wall exists between the Revolutionary War soldiers and their descendants. Therefore, with the advent of genetic research in genealogy it is the goal of The Grindle DNA project to use this new avenue in genealogical research to determine where genetic relationships may exist between these and other Grindle family lines.
