In response to: I firmly believe that Susannah, daughter of Alexander, was placed under guardianship of Thomas, her brother, and became his "daughter" by virtue of guardianship. I firmly disagree this was not done during this time period adoption was not even in practice she was his sister and had she been an heir in his esate she would have been listed as his sister not his daughter.She was his guardian but I have seen nothing that indicates she"became his daughter". Many of the "Younger" siblings named a daughter Susannah. With all of the long drawn out court case over Thomas Younger's esate that lasted some 20 years after his death,Had his sister Susannah been an heir there would have been verbiage to that effect,
