Angus MacAulay was born on the Isle of Skye, Scotland (ca. 1760), the youngest of twelve children. In and prior to 1873, he was a student of Divinity at Marischal College in Aberdeen. He was the schoolmaster in Portree on the Isle of Skye before being appointed by Alexander MacDonald as his factor in the Barony of Trotternish on Skye, 10 December 1789. On 24 March 1797, MacAulay was commissioned as a chaplain in the British Army, but left to further his studies and obtained his M.D. from Glasgow University in 1803. Angus began corresponding with Lord Selkirk in 1794, assisting him with his plans for emigrating Highland settlers to Prince Edward Island. Angus arrived on "The Polly" in Belfast, PEI, with other colonists in August of 1803.

MacAulay settled on one-thousand acres of land near the Pinette River. He conducted religious services in Gaelic for settlers in Belfast and surrounding areas. In addition to his role as minister, physician and speaker of the House of Assembly, Angus was also Selkirk's official agent. He married Mary (?-1857), daughter of Samuel MacDonald who was a Captain in H.M. 184th Highland Emigrant Regiment. Angus died on 6 December 1827. While he was still alive, Angus had set aside a parcel of his own land at Mount Buchanan for a cemetery. It is there that he and his wife Mary are buried.

Thomas Douglas, the Fifth Earl of Selkirk, was born on the 20 June 1771, on St. Mary's Isle near Kirkudbright, Scotland, seventh son of Dunbar Hamiliton Douglas and Helen Hamilton. With the death of his father in 1799, Thomas became the Fifth Earl of Selkirk. He married Jean Wedderburn in Inveresk, Scotland, on the 24 November 1807, and they had three children. Shocked by the effect of the highland clearances in Scotland, Douglas proposed to the British government the emigration of Highlanders to Prince Edward Island. The first ship of settlers set out in July of 1803 and arrived on PEI the following month, settling on land in Lots 57, 58, 60, and 62. Thomas Douglas died in Pau, France, on the 8 April 1820.

Alexander MacDonald appears to have been a landlord in Prince Edward Island. He was represented by Rev. Angus MacAulay.
