We might be somewhat related then.
This information was provided to me by a genealogy researcher of my family and is included in the Illinois Chapter of the Daughters of the American Revolution Archives.
My 6th great-grandfather the last Robert Terrell listed below was a descendant of the Terrell family who goes back to Normandy where Ralf, Sire De Tyrol De Poix and De Guermanville, son of Walter I, Count of Vexin and Amiens, lived around 995 A.D.
His father was Walerain, Count of Vexin who died in 965, his mother was Edelgard, great granddaughter of Charlemagne.
Sir Walter Tyrell who lived close to Paris on the Seine River and was a cousin and close friend of the Duke of Normandy. One of the Tyrells went with William the Conqueror to England and received large grants of land from him. The family was established in England by Hugh Terrell who went from Picardy to Essex in 1199. The first Terrell's who came to America were Timothy, son of Timothy Terrell of Allhollows London, who located in New Kent County, Virginia, others who settled in Virginia were Robert, William and Richmond. Timothy had son Robert and Joseph, and his son Robert had sons Edmond and Robert, both whom served in the American Revolution.
Robert traveled with my other 6th grandfather, Warner Ford, (Robert's daughter and Warner's son married) on two expeditions with George Rogers Clark to the Indiana Territory
They were both awarded property in Henry Co., Ky which they ended up selling and came back and settled in the area of Vincennes, IN.
