I am related to John and Anna Thompson who lived in Mercer County KY for at least a few years in the era around 1820.

One of their children was Elijah Thompson who was born in North Carolina in abt 1800. Elijah Thompson married Dianna Dean in Mercer County, KY on Nov. 23, 1820.

One of their children, John C., married Elizabeth Vanarsdall on 23 August 1843. Another of their children, Margartet Ann, married William Vanarsdall,but not sure of the date.

My gg grandfather Sigismund Scott married Nancy Thompson in Mercer County, KY on 23 Oct 1820. Nancy was Elijah Thompson's sister.

The correct John Thompson from Mercer County for our family tree has a Rev. War Pension No. of S36826.
