This Ancestry and DNA project was initiated by the descendants of Thomas St. John (1564-1625) of Uchel-olau, Glamorgan, Wales beginning in 2001. Thomas was the Master on the Popham Colony's ship, The Richard, that was taken captive by the Spanish off the coast of Florida. He bribed a guard for his freedom and returned to London a year later. His brother, Sir William St. John, Knight was a founder of the Jamestown Colony, 1st English Governor of the African Colony, and a Vice Admiral in the English Royal Navy. Two other brothers, Captain Nicholas St. John and Lt. Alexander St. John were killed at St. Lucia Island while trying to colonize it for England. These brothers were direct male descendants of Sir John St. John, Knight and 1st Baron St. John of Lageham, who descended from the first St. John, Raoul (Roger) d'Ivry (alleged). Raoul d'Ivry assumed the St. John surname in 1053 in the presence of William the Conqueror. Raoul became the 'man' of St.John at the end of the sea near Mont St. Michel in Normandy, France. His son, another Thomas of St. John, renamed the village St. Jean-le-Thomas.

There are many false claims regarding persons of the St. John surname. Historians have confounded specific individuals with others. Articles and books often describe confusing and conflicting claims. Unsubstantiated theories have been added to research sites as legitimate records. This site attempts to fix these issues with primary records and DNA testing by identifying as many living descendants and their direct lineages as possible.

Genetic Genealogy

We have two DNA projects at FTDNA
1) The St. John DNA project:
2) The Glamorgan Wales DNA project:
We can also review your AncestryDNA results if you share them with member 'thepoetz'
We are currently seeking any St. John males to test for our Y-DNA study of the various paternal lines. Other tests for female St. Johns are also proving helpful such as mtDNA and autosomal DNA for both male and female descendants.

Heraldry Genealogy

According to the College of Arms, any person who descends from a legitimate male descendant of Sir John St. John, 1st Baron St. John of Lageham inherit the right to his arms.

Secondary St. John Surnames

Several secondary St. John surnames have been created through the years including: de Port-St. John, Mewes-St. John, Poynings-St. John, Mildmay-St. John, and possibly others. While this project's main goal focuses on the original St. John lineage, it does include those other paternal families that share the St. John surname.
