1784 reg 1785  Sasine to Joseph Nisbett Registered on the 3 February 1785 by Elias Johnston On the 9th December 1784, in presence of the notary and witnesses compeared, Hugh Brown, weaver in Newmills, as attorney for Joseph Nisbett, tailor in London, only son now in life of the deceased George Nisbett of Crosstrees,
 No. 1946, dated March 14, 1539: John Kennedy of Culzeane who had been granted Auchinrugland in 1536, is deceased; his son, John Kennedy of Dalquharrane concedes a third of Auchinrugland to his mother Jonet Stewart 1550.-- On this date, archival sources show that James Nesbit was deceased, leaving Margaret and Mariota Nesbit, two daughters(should be sisters), as his heirs. The mother of these two daughters was Margaret Blair.
During the years 1536 up to 1550, it seems that Auchinrugland must have been in the care of whoever it was that had the wardship of the two daughters. Nor, have I any information about some widows' third's.
However, John Kennedy of Culzeane (son of Jonet Stewart) was granted Auchinrugland in 1536, after the Nesbit wardship had a lapse for 8 years (?).... William Hamilton and his wife Katherine Kennedy held Auchinrugland from 1539 up to 1550. The grants to these two must have carried limitations with them, giving possession coterminous with the length of the Nesbit wardship, as well as recognizing the land held by any surviving spouses
