Major Thomas Owsley is the father of all of the Owsley's in America, and his descendants have been diligent in researching his roots. The family name could be traced even further than shown here, were it not for a bomb in 1942 which destroyed the records. His mother's line, however, turns out to be very interesting. Dorothy Poyntz had a family name which has been traced back either eleven or thirteen generations, depending upon which branches are followed. Here's a document grabbed off of Ancestry.com.
Even more impressive is following the lines of Poyntz, Sydenham, Newdigate and others. Dorothea Poyntz would possibly have been amazed to see her lineage traced back about twenty generations, all the way to William the Conqueror. So here's another document! Many European monarchs can be found along these paths.
