My next step was to research a General Hull that in that era, no such luck, the only General Hull of that time, was in the American army during the war of Independence, but he died without issue.
Searching through google and other documents, I came upon a General who was in fact with Wellington, during his campaigns, but not a General Hull, but a General Sir Evelyn Pierrepont [1665-1726], 1st Duke of Kingston upon Hull, Arthur Brent had uncovered an important word.
General Pierrepont had one daughter, Anne Pierrepont [1719-1739] who married Alexander Livingston [1707-1766]. Anne died in childbirth, but her daughter Catherine survived.
With this discovery, I was able to then go on to expand my tree in the Livingston and Pierrepont families.
