Looking for information about Thomas Fairbairn (possibly Thomas James Alexander Brown Fairbairn) who married Mary Huggins 16 Sept 1807 in St. Vincent according to the register 1765-1820 page 132/260
https://eap.bl.uk/archive-file/EAP1013-1-4/.
Thomas seems to have been associated with Mr Gordon's estate Fairhall or Bentinck, in that in 1834 a Thomas Fairbairn attested to the report of 246 enslaved people on the property of James A. Gordon (possibly James Brebner Gordon). Fairhall was owned by James's Brebner Gordon's son James Gordon at the time of the slave register). Found this connection in documents of the Centre for study of the Legacies of British Slavery
https://ucl.ac.uk/lbs/estate/view/3644 I believe Thomas Fairbairn's father was a Colonel Thomas Fairbairn who died 4 Nov 1808 and was buried at Fairhall- per page 235/260 of the St. Vincent Marriage, Baptism and Burial Registry 1765-1820.
Looking at Fairhall I found mention of Thomas Fairbairn as a 'grantee' of Mr.Gordon's estate, land in the Parish of St.George under Governor Bentinck. gregg784.com/2017/04/30/manuscript-collection/?print=pdf Document held in Bentinck Collection at Hamilton College New York)
Thomas's wife Mary Huggins was, I believe, the daughter of James Huggins (1752-1837) and sister of Joseph Stanley Huggins. Note one of Joseph's sons was Thomas Fairbairn Huggins presumably after his brother-in-law.
I also note James Huggins wife Mary (Evans) Huggins who died in 1811 left slaves to her daughter Mary Fairbairn

I am linking these pieces - hoping for others researching Fairbairn or Huggins have more information.
I note Mary Huggins also leaves slaves to 7 other children - 6 match my tree but she names Ann LaCroix - I have an Amy Huggins (1786-1861) in my tree and think she may be this Ann.
