Nearly all of the Rambo families in the United States are descended from one common ancestor: Peter Gunnarson Rambo, a Swedish colonist who landed on the shores of the Delaware River in 1640 at what is now Wilmington, Delaware. This history of the Rambo family describes Peter and his six children and lists their descendants who have migrated into every state of the Union. Some of the family lines have been extended to the 12th generation with their children comprising the 13th generation. Gunnar Rambo, oldest son of Peter Gunnarson Rambo, and descendants of his oldest son, John, and his daughter, Brigitta (Rambo) Holstein, are the focus of this second volume of the Rambo Family Tree series. Gunnar was an active member of Gloria Dei Church, became a large landowner, and in 1685 was a member of the Pennsylvania Provincial Assembly. Gunnar and wife Anneka Cock lived at Shackamaxon [now part of Philadelphia] for 20 years until he sold that property in 1697 and moved to Matsunk [now Swedesburg]. This volume lists all their children and many generations of descendants although generally no people still living will be recorded herein. Rambo is the primary surname in this book although extended families are recorded by daughters who married Coates, Cramer, Cremer, Dehaven, Eyestone, Fulton, Hager, Holstein, Hughes, Mattson, Priest, Rider, Rittenhouse, and Williams husbands. A third edition of this genealogy is being compiled as you read this. Please help to improve this genealogy by sending corrections, additions and improvements to me at rsbeatty@gmail.com. With your help, the third edition can be even better. Thanks. Ron Beatty, December 2009
