Yes ,Yes Thomas was Susannah's Guardian some 60 years prior to the writing of his own will. I have spoken to two lawyers who have read the Chauncery suit and they like me do not see any indication that Thomas is referring to His Ward Namely his sister who would be atleast in her 70's at the time he wrote his will.Nor do the two Lawyers I spoke with believe that the later dispute in the 1820's would have referred to some of Thomas's children being Susannah's half sister and some being her full sister if she was idneed their "Aunt". They also agree that the practice of legal adoption was not in place in the 1700's in America at best she would have been listed as Thomas' sister or his Ward not his daughter. I believe the Susannah in the Chauncery suit is Thomas's natural born daughter not his sister. you are welcome to your opinion and your interpretation but I do not see any evidence in Thomas Youngers will or the later Chauncery Suit that supports what you are saying is valid. I see evidence that Thomas's daughter is dead by the time of his Chauncery suit and the estate is being divided with the heirs of Susannah's full siblings and her half siblings indicating that Thomas Younger was married twice or his wife was married twice not that she was the Aunt and Younger sister of Thomas..The Lawyers I spoke with agreed that because of the dispoute if Susaannah ahd been Thomas's sister and his ward it would have been sateted as such in the will and the chauncery case. These are my last comment on this subject. Jerry
