We were showing this man's parents as John Lyon, 7th Lord of Glamis and Alice Holmes -- but per Douglas's Scottish Peerage, vol. II, pp. 563-564 and John Lyon's entry in the Dictionary of National Biography, John's only wife was Janet Keith, and they only had three children: John, Thomas, and Margaret.
Would any 1500s England specialists like to help take a crack at figuring out the details on this man, and maybe who he belongs to?
