Peter Hume Brown, Dictionary of National Biography… (1912)
“ After a long and painful illness he died at his home at Duddingston, near Edinburgh, on 12 March 1904. Law was married on 15 April 1880 to Wilhelmina Frederica, daughter of Captain Allen of Errol, Perthshire, by his wife Lady Henrietta Dundas, and left one son, Duncan, and five daughters. Law's main historical interests lay in the sixteenth century, and specially in its religious and ecclesiastical aspects. In his treatment of contending religious forces he shows remarkable freedom from partisanship, and everything that he wrote was based on all the accessible sources relative to his subject. ”
