Robert, I am Susan in Texas, USA. I have been the recipient of the most generous gentleman in UK! I have been searching for my Garstin relatives. He showed me, through many emails, that my heritage goes back to Robert Colebrooke. Then searching this question somehow popped up. I asked my benefactor about your question to which he sent the following answer:
year of her age, Mrs. Mary Jones wife of Robert Jones M. D. of Carmarthen”. Source. Hereford Journal 19 February 1794. She was born 1739.
Dr Robert Jones MA MD of Merionethshire (Wales) qualified at Edinburgh; he wrote two books;
1. "An inquiry into the nature, causes, and termination of nervous fevers : together with observations tending to illustrate the method of restoring His Majesty to health, and of preventing relapses of his disease. By Robert Jones, M.D. And Member of the Royal Society of Antiquarians At Edinburgh.

(he refers here to the Madness of King George III)

He also lectured. There is an advert in Sept 1788 in the Salisbury and Wiltshire Gazette and in Oct 1788 in the Bath Chronicle for paid lectures that a Dr. Robert Jones M.A. and M.D. of Castle Street Salisbury. He intended to charge 5 guineas if he could get 20 people to attend a lecture and appears to be available at home for consultations on Tuesdays and Saturdays from 10.00 till 3.00 at a cost of ten shillings and sixpence.
In these adverts Robert Jones describes himself as a member of the Royal Society of Antiquarians of Edinburgh (the Royal Society in Edinburgh I believe), and the Society for the encouragement of the Arts, Manufactures and Commerce, Adelphi, London (now the Royal Society of Arts).

+Comments added to margin of Robert Colebrooke.'s will 1794
On 3 day of July 1794 Administration (with the will unadministered) ..... goods, chattels, codicils of Robert Colebrooke formerly of Chilham Castle in the Co Kent but late of Soissons in the Kingdom of France Esq deceased is unadministered as well by Francis Atkinson one of the executors as by Mary Jones/wife of Robert Jones, Doctor of Physic the Residuary Legatee for life named in the said? will is now also deceased, was granted to Powlet Welbore Colebrooke other
?? Colebrooke Esq one of the residuary legatees, substituted in this? will having been first sworn duly to administer. Daniel Bureau the other Extor named in the will has fully renounced the execution thereof"
I suspect that Sophie Sorfebure of Paris -mother Madame Angelique, and Robert Stockdale were further children of Robert Colebrooke, all getting their £20 token. It must be remembered that Robert Colebrooke and his brother Sir George had both fled to France to escape their creditors, a somehat risky enterprise seeing that this was on the eve of the French Revolution. Luckily for Sir George, he seems to have escaped and reestablished himself with the East India Company; he died in 1809 in peaceful Bath (not the bath in which Marat was murdered by Charlotte Corday 1793!). See Wikipedia.
I hope this helps your search. At the very least, you and I wind up as cousins! I am related FROM Robert Colebrooke to Charles Garstin Smith and Mathilde Sanderson. They had children, August Edward Garstin Smith, Alfred Herrman Garstin Smith, Marian Alice, Lilian , and Reginald. All immigrated to Chicago, Illinois, USA. Charles Garstin Smith was born of a dalliance with a "local" woman in India, his father was Edward Garstin.
Good luck with your further searches. I hope I saved you some time!
