The McLennan Family of Loretteville and Montréal arrived in Canada in 1802 from Scotland. Hugh Stewart McLennan was a Montréal businessman, active in the grain trade for many years. He founded the McLennan travelling libraries to provide library facilities to western Canada in cooperation with clergy and teachers. Of his thirteen children, two of the better-known were William, a notary and writer and Isabella, a benefactor of McGill University.

Archibald Woodbury McLelan was born on December 20, 1824, in Londonderry, Nova Scotia.

He was a shipbuilder, shipowner, and politician. He was educated in Great Village, Nova Scotia, and Mount Allison Wesleyan Academy in Sackville, New Brunswick before joining his father's shipping and retail business. McLelan went into partnership with his brother-in-law, John M. Blaikie, with whom he built ships on the Great Village River into the early 1880s. Upon his father's death in 1858, he succeeded him in the House of Assembly. Strongly opposed to Confederation, he was elected as the first federal member of parliament for Colchester as an Anti-Confederate. In 1869, he reconciled himself to Confederation and was summoned to the Senate of Canada where he sat as a Liberal-Conservative. He resigned from the Upper House to run again for the House of Commons of Canada in the 1881 federal election and was returned to parliament as a Conservative. He served as the Minister of Finance from 1885 to 1887 in the second administration of Sir John A. Macdonald. Following this position, he became postmaster general and was responsible for introducing the parcel post system into Canada. From 1888 to 1890, he served as the 6th Lieutenant Governor of Nova Scotia.

In 1854, he married Caroline Metzler (1832–1918). He died on June 26, 1890, in Halifax, Nova Scotia.

John McLean (MacLean) was born on November 17, 1828, in Portsoy, Banffshire, Scotland.

He was a Church of England bishop and educator. He graduated with an M.A. from King’s College (University of Aberdeen) in Scotland, in 1851 and was ordained in the Church of England in 1858. He came to Canada as curate of St. Paul’s Cathedral in London, Ontario, serving up to 1866 when he came to Red River, Manitoba, as Rector of St. John’s Cathedral and Archdeacon of Assiniboia. He also served as Professor of Divinity and Warden of St. John’s College, Winnipeg. During the Red River Rebellion (1869-1870), McLean counselled moderation. He frequently served as a go-between in complex negotiations over Riel’s prisoners and helped convince Riel to spare the life of Charles Boulton. He received honorary degrees from Trinity University, Toronto, Bishop’s College, Lennoxville, and Kenyon College, Ohio. In 1877, he was a member of the First Convocation of the University of Manitoba. In 1874, he was consecrated as the first Bishop of Saskatchewan.

In 1861, he married Kathleen Wilhelmina Flood (1842–1897). He died on November 7, 1886, in Prince Albert, Saskatchewan.
