John Campbell, Lord Stonefield

The Hon John Campbell, Lord Stonefield FRSE (c. 1720–1801) was an 18th-century Scottish lawyer who rose to be a Senator of the College of Justice.

[2][3] However other sources give Captain Ogilvy's father as Alexander Campbell of Stonefield (implying illegitimacy).

If young John was indeed the son of Alexander Campbell, this complicated relationship would make him half-brother of his own (adoptive) father.

As a third, and perhaps more logical conclusion, Archibald was perhaps truly the biological father of John, but conceived very young and definitely out of wedlock.

[8] In 1756 he bought Elphinstone Court in Edinburgh, the home of the late Peter Wedderburn, Lord Chesterhall, whose son Alexander had inherited the property but had no use for it, as he worked in London.

[6] Following his death his place as Senator was filled by Alexander Fraser Tytler, Lord Woodhouselee.

Lord Stonefield sat as one of the Judge of the Court of Session exactly thirty-nine years, having been appointed to the Bench on 16 June 1762.

[14] In 1791, following Grace's death, he married Miss Phoebe Lloyd (c. 1756-29 Sep 1818), who was buried at St George's Hanover Square in London.
