John Schmeeckle has completed the first template trail to a surety baron at WikiTree.
Beginning with Colonial ancestor Agnes Harris (Edwards, Spencer) up to Surety Baron William Malet, any descendant of Agnes can trace the generations from her to William with the Magna Carta Template on each succeeding ancestor.
Just look for the Magna Carta template as seen below.
Sandy Culver has started the template trail from Rev. Charles Chauncy to Magna Carta sureties Roger and Hugh Bigod.
I'm working on the trail from Olive Ingoldsby (James) to Saher de Quincy, Magna Carta Surety.
See our Gateway Ancestors page for more Colonial immigrants who are descended from the surety barons of Magna Carta.
