Glad to see you are still searching out your roots. Your earliest known ancestor is Samuel Coe, who was born in 1728 and lived in Calvert County, MD. He first appears on record in Calvert County when he recorded the birth of his son William, November 9, 1757. He recorded the birth of his daughter Ann, March 25, 1760. On August 31, 1770, he made a deposition on Calvert County stating that he was 42 years old and had known the complainant John Morsell seventeen or eighteen years. In 1778 he signed an oath of fidelity and allegiance, pledging his support for the newly formed American government. In 1782 he paid taxes on a 75-acre farm known as "Golden's Folly," located at the mouth of Parker's Creek. He was taxed on a slave, four horses and six head of cattle. On January 1, 1782, the vestry of Christ Church, Port Republic, Calvert County, "struck off to Mr. Samuel Coe for 200 lbs. of tobacco," a tract of land known as "The Gore." He last appears on record in 1796.
Although Samuel Coe's parent family has not been documented, there is some suggestion that he could have been a son of Richard and Jane Coe of Charles County, MD. Richard Coe, who must have been born about 1780 and died in Charles County in 1757, was a son of another Richard Coe, who first appears on record in Maryland in 1651. It is known that Richard Coe II had a son John born 1716 and a son William born 1727. It is conceivable that he had a son Samuel born in 1728. Charles and Calvert Counties are separated only by the Patuxent River. When the above mentioned John Coe died in 1763 in Prince George's County, MD, Samuel Coe was made guardian of his children. This may have been John Coe's oldest son Samuel, however.
I trust that this is somehow helpful.
