The McEnroe brothers were born to their American parents – John Patrick McEnroe and Kay/Katherine Tresham.
Their dad was the son of an Irish immigrant, who made the infamous admission that his son John “was made in Belgium but born in Germany” during a news appearance in Belgium.
John Patrick McEnroe was serving with the United States Air Force then. The McEnroe brother’s grandmother was from County Westmeath, while their Irish paternal grandfather was from Ballyjamesduff in County Cavan.
