"Robert Hamilton was born in Pennsylvania on June 17, 1765, and died at his home in Kentucky on June 17, 181 7, he was married to Mary Eward, who was born in Virginia on May 20, 1774, and died at the home of her son, R. M. [Robert Marshall] Hamilton, northeast of Greensburg, in this county, March 15, 1848. They were married on June 19, 1794 in Kentucky. Robert Hamilton emigrated from Pennsylvania to Kentucky when the latter state was admitted to the Union and recruited a company and captained it during the War of 1812, serving against the Indians. He died in 1817 and his body was buried in the old Concord churchyard in Nicholas county, Kentucky. Afterwards his remains were brought by his descendants and placed beside those of his wife in the Kingston cemetery.
"Robert Hamilton was the son of William Hamilton, a Scottish Presbyterian who emigrated from the north of Ireland about 1750 and located in Pennsylvania, whence he later emigrated to Kentucky, settling on McBrides creek, then in Bourbon county, now Nicholas county, being among the earliest settlers of that section. William Hamilton married Isabella Thompson, in Pennsylvania, to which union were born seven children, namely: William, who was killed while battling with the patriots for independence during the Revolutionary War; Alexander, who settled in Clark county, Indiana; Thomas, who married Charity Welch and died near Carlisle, Kentucky, in 1803; Samuel, who married Jeannie Sweeney; Robert, who married Mary Eward; Eleanor, affectionately known as "Nellie," born on May 12, 1758, married John Blair and died on December 25, 1827; and Isabella, who, about 1808, married Samuel Hindman."
