The oldest of my McMenamy ancestors, John McMenamy, was born in Northern Ireland June 17, 1738 and died September 12, 1800 in Caswell County, NC. Some of his descendants moved from NC to TN and then to TX, where I am. The children of the brother of my 3rd great grandfather moved to Greene County, MO about 1844. I suspect that I am related to some of the McMenamys in MO.
I would be glad to share my information if there is a connection.
