I believe that it was George Carpenter, 2nd Baron Carpenter, Earl of Tyreconnell but some official records contradict this buly not acknowledging that he was a son. For context, Conrad's son was Admiral Sir James Carpenter. I find it odd that the latter could generate such an esteemed career unless his dad's lineage was special.
If Conrad's link to the 2nd Baron Carpenter is confirmed, I am an 8th cousin of the current Marquees of Waterford, a 6th cousin to the current 7th Baron of Leconfield, and a direct descendent of Drieu of Normandy (1066), who was one of William the Conqueror's knights. I think!
Any help would be greatly appreciated!
