The Buchanan and Edmiston/Edmondso n Families have been close for several generation. Samuel arrived in the 1740's in Agusta Co. ,VA and lived next door to John and Robert Edmiston. With them, he and his family moved down to Washington Co.,VA in the 1770's, and the close relationship continued. There were many Buchanan-Edmiston intermarriages amongst the siblings. John and Robert may have married a Buchanan, as well as Samuel marrying a Edmiston.

"Samuel probably came to Augusta Co., VA from Chester Co., PA. In 1746 he is one of 7 elders ofthe New Providence congregation (Presbyterian) of Augusta Co.His name appears on many church records including a 1771 deedfor the land upon which the New Providence Church was built. In1773 he and his family moved to that part of Fincastle Co.,which would become Washington Co., and he was one of thesigners of a petition to Rev. Charles Cummings (June, 1773).His will was written in Oct 1774 and was proved in court 18March 1783 (Washington County Will Book I:83) Landtransactions link him to two other Buchanan families and may indicate family ties. The first is the purchase in 1755 of 711 acres in Augusta Co., for Matthew Buchanan of Chester Co., PA. Later Matthew sold this land and again Samuel acted for him. One of Matthew's sons eventually settled on land adjoining the Buchanan farm in Washington Co. In the second case, Samuel purchased 393 acres in 1756 from John Buchanan of Reed Creek (this is the John Buchanan who married the heiress of James Patton). He was the son of James and Jane Buchanan and itappears that after James's death, Jane came to live withSamuel's family in Augusta County. This has led some to believe that Samuel was the son of James and Jane.
