Portrait of Agnes Mary Clerke Agnes Mary Clerke,  Dictionary of National Biography… (1890)

“ By the marriage of his daughter, Janet, with John Gregory, the hereditary mathematical genius of the Andersons was transmitted to the Gregorys and their descendants. James Gregory's education, begun at the grammar school of Aberdeen, was completed at Marischal College. His scientific talent was discovered and encouraged by his elder brother David (1627-1720) [q. v.] , and he published at the age of twenty-four ‘Optica Promota’ (London, 1663) , containing the first feasible description of a reflecting telescope, his invention of which dated from 1661. ”

Portrait of Walter Scott Walter Scott,  Rob Roy (1818)

“ James Gregory (by descent a MacGregor) , the patriarch of a dynasty of professors distinguished for literary and scientific talent, and the grandfather of the late eminent physician and accomplished scholar, Professor Gregory of Edinburgh. This gentleman was at the time Professor of Medicine in King's College, Aberdeen, and son of Dr. James Gregory, distinguished in science as the inventor of the reflecting telescope. With such a family it may seem our friend Rob could have had little communion. But civil war is a species of misery which introduces men to strange bed-fellows. ”

Agnes Grainger Stewart,  The Academic Gregories

“ Two hundred and fifty years have obliterated what must once have been written, and the Dee is gaining ground from the graveyard at every time of spate. The old church stands and the manse, which has been turned into a farmhouse, but that is all.
There is a memorial of John Gregorie and his wife in a mortification for the education and maintenance of ten poor orphans ‘within the said Burgh’ of Aberdeen.
John Gregory left three sons, Alexander, who was served heir to his father’s very considerable property in 1651, David, known as David of Kinairdy, and James, the great professor of astronomy.
