I expected some responses by some Rev. War people on this, so maybe you should post it again. But a very famous example of this would be William and Benjamin Franklin. William was Ben's illegitimate son, acknowledged and brought up in his household given an education and treated well, even indulged. In 1763 with Ben's influence, William was appointed royal governor of new Jersey, and was still governor in 1774 when Ben traveled to England. Ben thought he was going to be answering some questions from the Privy Council and expected civil treatment: instead he was subjected to a torrent of public abuse and jeering, and stripped of his position of Postmaster. That pretty much decided him on supporting independence for the Colonies; but William was not of the same mind. While Ben was serving as ambassador to France for the rebels, William was a Loyalist, doing whatever he could to stop them. He was captured by the Continentals, imprisoned for two years, exchanged for another prisoner, and sailed to England. He made attempts to reconcile with his father, but Ben would never reconcile with him .

Here is an article by Sheila Skemp on the break, and why Ben might have felt so strongly.
