Charles Frederick Gurney Masterman was born on October 24, 1873, in London, England.

He was a British Liberal politician and author. He was educated at Weymouth College and Christ's College, Cambridge. As one of the best speakers, he became President of the Cambridge Union and joint Secretary of Cambridge University Liberal Club from 1895 to 1896. In 1897, he was awarded the Arnold Gerstenberg scholarship, returned to Cambridge and, in 1900, he was elected a fellow. He published books "From the Abyss" (1902) and "In Peril of Change" (1905) and contributed articles to the Independent Review, The Pilot, The Commonwealth, the Daily News, The Speaker, and The Nation. He was elected as Member of Parliament for West Ham North (1906-1910) and Bethnal Green South West (1911-1914). Masterman played a major role in writing parts of the Finance Bill, the Development Bill, the Shop Hours Bill, and the Coal Mines Bill and was responsible for the passage through parliament of the National Insurance Act 1911. In 1914, he was appointed Chancellor of the Duchy of Lancaster, a post he held until 1915. From 1914 to 1917, with a background in journalism, he served as Head of the British War Propaganda Bureau, known as Wellington House. Masterman played a crucial role in publicizing reports of the Armenian genocide to strengthen the moral case against the Ottoman Empire. After a few unsuccessful attempts to get reelected in the early 1920s, he focused on writing and published several books, e.g., "How England is Governed" (1921) and "England after War" (1922).

In 1908, he married Lucy Blanche Lyttelton (1884–1977). He died on November 17, 1927, in London, England.

Montrealer Philippe Masson was born on October 4, 1911, in Terrebonne, Quebec, the son of Joseph Masson, Seigneur of Terrebonne, now a vibrant community northeast of Montreal. Little is known about the life of Philippe Masson apart from the fact that he suffered from a chronic illness and died at the age of 32 on August 1, 1944. His remains are buried in the Parish church in Terrebonne. Despite his illness, he developed an interest in the collecting of ephemera. He developed a passion for the collection of bookplates, which he pursued in a single-minded fashion. In addition, he methodically catalogued and described his collection in fifteen volumes.

Louis Rodrigue Masson (baptized Louis-François-Roderick) was born in 1833 in Terrebonne, Lower Canada, and died in November 1903, in Montreal. He was the son of Joseph Masson and Marie-Geneviève-Sophie Raymond and had two brothers named Wilfrid and Isidore-Édouard-Candide. In 1856, Masson married Louise-Rachel McKenzie, the daughter of Marie-Louise Trottier Desrivières and Lieutenant-Colonel Alexander McKenzie of Terrebonne. They had ten children, five of whom reached adulthood. In 1883, Masson married Cecile Burroughs, the daughter of Léda Larue and John Henry Ross Burroughs, who was a prothonotary at the Superior Court of Quebec. They had three children. Masson became head of the Masson clan and administrator of its assets, including the property, the seigneurial mill, and the various enterprises bequeathed to him by his father. Although the seigneurial regime was abolished in 1854, the Masson family remained identified as a seigneurial family. In the unrest that followed when Rupert’s Land was acquired by Canada in 1869, Masson opposed his colleagues in the name of the rights of the Métis and First Nations. In 1871, he defended the Catholics that demanded that the federal government disallow the provincial law.

Joseph Masson was a Montreal businessman, banker, and politician. Masson was born in Saint-Eustache, Quebec, on 5 January 1791, to Antoine Masson and Suzanne Pfeiffer. After attending school, he started working as a clerk in 1807 for Duncan McGillis, a British merchant working in Saint-Benoît (now Mirabel, Quebec). Masson moved to Montreal and in 1812 was hired by Hugh Robertson, owner of Hugh Robertson and Company of Glasgow. In 1815, after working for Robertson for a few years, Masson negotiated himself a senior partnership and the firm's Montreal-based company became Robertson, Masson and Company. By 1819, Masson had a 50% share of the Montreal firm. He also purchased several vessels to better control and reduce costs associated with shipping. Masson was involed in efforts to build and improve canals and railways, including the Champlain and St Lawrence Railroad, Canada's first public railway. In addition to his success in business, Masson also began to pursue banking, buying shares in the Banque de Montréal in 1824, and joining their board of directors in 1826. He was also involved in politics, serving as a member of the Legislative Council of Lower Canada between 1834 and 1838, Montreal militia captain in 1823, and justice of the peace in 1836. In 1832, Masson purchased the seigneurie of Terrebonne. Masson married Marie-Geneviève-Sophie Raymond on 6 April 1818 in La Prairie. They had 12 children together. Masson died in Terrebonne on 15 May 1847.
