It is also worth mentioning that in parish records of Aberdeenshire, 'of' a farm usually meant it was owned and 'in' meant that it was tenanted. Large farms had several tenants 'in' them and were sometimes designated a 'toun' or 'town'.
Count Leslie (our Patrick's granduncle) was a Count in the Holy Roman Empire so not part of the Scottish nobility per se. Patrick was definitely a Count. I quote 2 references below ...
1."Walter Leslie's patent of the dignity of Count of the Holy Roman Empire was granted to him and his two brothers, William and Alexander, and their heirs, that, in case he died without issue, they might succeed him in his titles and estates.
"Being possessed of great wealth, Water Leslie frequently remitted sums of money to his brother Alexander Leslie, fourteenth Baron of Balquhain, and his nephew Patrick Leslie (1640 - 1710), fifteenth Baron, and enabled them to retrieve their estates, then very much embarrassed by the extravagance of former possessors.
Walter, Count Leslie, died at Vienna 4th March 1667, aged sixty-one years, and was buried with great pomp in the Leslie chapel in the Scotch Benedictine Abbey there. He was succeeded by his nephew James, second Count Leslie who died 1694."
2. Having no issue, Walter entailed his estates on his nephew Count James, eldest son of his brother, Alexander Leslie, fourteenth Baron of Balquhain, and his heir-male; whom failing, on Patrick Leslie, younger son of the said Alexander Leslie, and his heir-male; failing whom, on the heirs-male of his father-in-law, Maximilian, Prince Dietrichstein; family whom, on the heirs-female of the said James and Patrick Leslie, his nephews, when the entail was to be exhausted.
Patrick Leslie, after his succession to the Leslie estates in Germany, on the death of his brother Count James in 1694, also made additons to the Balquhain property, purchasing the lands of the barony of Insch, Boddam, Greenhall, Muiryheadless, Knockenbaird, Scotstown, and Aquhortes.
