The only George McQuitty to be found in Griffiths Valuation of Ireland was
1861
George McQuitty, Townland of Cubbindall, Parish of Ballymoney
leased +29 acres of land and a house and offices and also leased land to a Mark Buckly.
Quite a prosperous farmer I would say, so that would fit in with your story.
Let us know if that is the right marriage.
