The Birth Date is a rough estimate. See the text for details.


James was born between 1710–1720, the son of John Ferguson of Belfast. He matriculated "Pharmacopoiæ" from the University of Glasgow in 1739.[1]

Dr. Ferguson married first, Sarah Clark, daughter of Jackson Clark (1698–1754) of Maghera, county Derry.[2] The issue of this marriage was a son, George, who died in 1776.[3]

After his wife's death in about 1757,[4] Dr. Ferguson remarried to Miss Jane Stephenson of Killyfaddy, parish of Armagh (later Lisnadill) and county Armagh.[2]

Dr. Ferguson's interests were not confined to the practice of medicine or apothecary. In 1764, Dr. Ferguson received £300 from the Irish Linen Board for the successful application of lime in the process of bleaching linen.[5] In 1766, he:

published an excellent experimental Essay upon the use of leys and sours in bleaching, in which he has greatly elucidated this subject. With the intention of teaching bleachers to ascertain the quantity of carbonic acid fixed in ashes, and in lime-stone, and consequently of ascertaining the proportional quantity of lime, from different kinds of stone, which should be mixed with any quantity of the different kinds of ashes, and which would require all the gas contained in them, to restore the lime to a mild insoluble state. He ascertained the quantity of the gas in each kind of stone and in each kind of alkili he had an opportunity of trying.[6]

Known issue of this second marriage includes John Stephenson Ferguson (1761–1833) and James Ferguson (d.1834), both linen drapers of Belfast.

Dr. James Ferguson died on the 29th December 1784, aged about seventy years.[7] The Belfast News-Letter published the following death notice (the characters given [within square brackets] were illegible in the original text):

Died, on Wednesday morning last, of a fever, [D]r. James Ferguson of this town. The universal [re]gret of his loss is the best eulogy on his many vir[tu]es.—Every relation in life he supported in a manner becoming and exemplary. As a physician of [--]ng experience, his decease must be severely felt; [--]t more particularly by the poorer classes, to which [h]e paid such a degree of disinterested attention du[ri]ng a life of medical practice, as strongly indicated [by th]at philantropy and general worth by which his [c]haracter was eminently distinguished.[8]
