William Black and his descendants

The first 2 pages give a description of the movement of the Scotch-Irish Black family from Edinburgh, Scotland to Londonderry, Ireland to America. (He writes in general terms and doesn't give any sources or references.) They left for religious freedom and had been through several hundred years of turmoil. "They landed on the Delaware River above where Wilmington now stands, between the years 1710 and 1720. Many of them remained here while others settled on the Brandywine River in Pennsylvania." The Scotch-Irish families are described as farmers by trade and Presbyterian. They were drawn to PA for the rich land and religious freedoms. Further described as firm, tenacious, resolute and ready to fight because of their hard times in Scotland and Ireland. Again, the writer gives no other information about the Black's beginnings in Edinburgh or Londonderry. The Immigrant, Alexander Black, was born aboard the ship that sailed to America according to an interview with Major George Black (included in the book). He is next heard from when he buys property on the Cowpasture River, VA in 1746. "It appears almost certain that he came into VA from PA with other Scotch-Irish who settled in VA at that time, and that his parents died in PA as no trace of them is found in the Augusta County Records." His wife was unknown, he qualified as a Foot Soldier in 1752 and he died in 1764. His children were; William, Alexander, Rachel, Mary, Nancy and Elizabeth (Peggy). The majority of the book gives the descendances of the Immigrant's children.
