He died in 1811 and was buried in St. Paul's Cathedral.
Life with Boswell:
Boswell dined with Mylne at Lord Eglinton's on November 23, 1762 in London.
Note 1: "they had walked most of the way across France and down through Italy and were leading a hand-to-mouth existence in Rome on an allowance of £30 a year from their father" according to John Fleming's Robert Adam and His Circle, in Edinburgh & Rome, p. 188 (available at AbeBooks.com)
A. E. Richardson's biography Robert Mylne: Architect and Engineer 1733 to 1811 (1955) is the authoritative work on Mylne. It is usually available via AbeBooks.com.
