Before I repost on the James Bryson of McVickersland, I want to mention a couple of Deeds unearthed by Gilby.
The first is ROD 797/255/538390
https://www.familysearch.org/ark:/61903/3:1:3Q9M-CSJ7-Q9HQ-5?i=163&cat=185720I will not attempt to transcribe this but in summary a John Bryson obtained the lease of a 51 acres farm in Ballybracken from a John Sittlington who was granted that lease in 1769. This JOhn Bryson was the father of James Bryson (who became his heir) and his brothers John, Alexander and Hugh. James Bryson transferred that lease, which he had inhertited, to his brothers in 1779. JOhn Bryson of Ballywee was witness to that transfer.
By 1823 Alexander had been granted part of that farm by his brother Hugh (who died shortly after) so at the time of this deed owned half the farm, and this deed records the transfer of that half of 51 acres to a John Bryson of Ballybracken. Alexander was presumably the brother of the John Bryson of Ballybracken who was born c1752 and died 1812, so the John Bryson of Ballybracken of this 1823/24 deed, was probably Alexander's nephew. John Bryson, who was the oldest son of John Bryson born c1752,was born c1785 and married Margaret Ballah.
The other deed is dated 1825. I hope the link works. Date: 3 Nov 1825
https://www.familysearch.org/ark:/61903/3:1:3Q9M-CSJ7-SS32-6?i=246&cat=185720This deed refers to another memorial deed dated 1 Nov 1803 between John Bryson of Ballywee and James Bryson of Holestone, who were brothers. James Bryson of Holestone erected the Tombstone transcribed below which says their father James Bryson died 1 June 1803.
This stone is erected by James Bryson of Holestone in memory of his wife Isabella who died 1st April 1797 aged 41. Also his father who died 1st June 1803 aged 71. Also his mother who died 1st May 1807 aged 65 and two of his children. Also the erector who died 20th February 1832 aged 64 years.
This James who died 1803 (born c 1732) was possibly the James Bryson of "then of Ballyvoy" who was the heir of John Bryson in the first deed.
