My gr-gr-gr-gr-gr-grandfather's brother was George Klein(1740-1795) who moved from Berks County, PA to Rockingham County, VA. He was married to Elizabeth Altaffer(1740-1825) and they had the following children: John Kline, Joseph Cline, George Kline, Frederick Kline, Michael B. Kline, and Catherine Kline.
I'm looking for information on the descendants of his children. I also need the exact birth and death dates of Elizabeth. I only have the years.
