In 1785, Samuel Boyd, a veteran of the American Revolution, married Isabella Higgins, who in her younger years had once accompanied Andrew Jackson. It appears that Samuel was always looking for a larger homestead and better soil. Not long after they were married, the Boyds moved from Tennessee to Madison County, Kentucky. Sometime around 1799, with young children, they moved again to a place on the Cumberland River called Horseshoe Bend. Eventually, the family went as far west as Adair County, which in the early nineteenth century was considered "a wilderness part of Kentucky"
Around the time the Boyds moved to Adair County, the great Kentucky revival reached that part of state. In the early days of their marriage, Samuel and Isabella identified as Presbyterians. But now they sided with the so-called Newlights and their home became "one great center for the meetings."
During those years, Barton W. Stone, William Kincade, Moses and Reuben Dooley and David Purviance often preached there. Samuel would occasionally address the gathered crowds with a word of exhortation. Later, he "became an earnest minister of the Gospel." In the summer of 1809, leaders among the Kentucky Christians publicly set him apart as one of their preachers.
By 1811, Samuel Boyd had nine children and was also "blest with flocks and herds." Looking for enough land to accommodate a large family and his successful livestock operation, he decided to move yet again. This time he went to Indiana, where he would spend the rest of his life.

The quotation is taken from page 126. As one might guess, along the winding Cumberland River there is more than one spot known as Horseshoe Bend. But given the time period, this is likely a reference to Horseshoe Bend in present-day Whitley County, Kentucky.
