I was also just looking at another James Bryson family trying to work out if there’s a connection…
1829 - PRONI D509/2479
Lease of 24 acres 3r. 4 per. I.P.M. for three lives renewable forever (See D509/690) - Consideration: £150 - Rent: £7.7s.9d. p.a. plus fees of Most Hon. George Augustus, Marquess of Donegall to James Gawn, Donegore, Co.Antrim and James Bryson, Jr., Holestone, Co. Antrim (Trustees for Arthur and Samuel Armar) relating to Ballyclaverty, Co. Antrim.
He’s probably the same James Bryson who was father of:
- Robert Bryson (c1830-1897) m. (1860) Sarah Caldwell.
- Mary Bryson (c1838-1903) m. (1858) William Samuel Bell.
Both of them were of Ballyclaverty when they married, and both mentioned Andrew Gawn (of Halftown) in their wills.
Edit: Mind you, James Bryson and James Gawn were only acting as trustees in 1829, so perhaps that James Bryson of Holestone never moved to Ballyclaverty.
