David, Earl of Huntingdon was the youngest son of Henry Earl of Huntingdon, who was heir to King David I of Scotland. David had one surviving son in John of Scotland, John died without issue, and passed on the Earldoms of Huntingdon and Chester to his sisters.
What I am wondering is what if he had had a son to succeed him upon his death in 1237? If that son was around when ALexander III of Scotland died in 1286, and had a family of his own, and say Margaret Maid of Norway still dies in 1290.
Now it seems the Great Cause is avoided as there is a legitimate male descendant alive with the best claim, and so John of Scotland's son would ascend the throne. What would happen then?
Considering Henry (that's the name of John of Scotland's son) would be Earl of Huntingdon and Earl of CHester, he'd be quite powerful in England as well, so might Edward be a bit more wary?
