[2] Her parents were Pierre-Ferdinand Renault (1853–1912) and Amanda Montminy (1853–1922).

Pierre-Ferdinand Renault was a Beauceville businessman (originally from Ste-Claire-de-Dorchester, Quebec) and changed his family name from Renaud.

Renault met Louis St. Laurent at a party in Quebec City in 1906 while he was working as a lawyer,[3] and they married in 1908.

[2] In 1951, she moved the family to Ottawa, after the government purchased an official prime-ministerial residence at 24 Sussex Drive.

She would tour with her husband, but she refused to fly and never became reconciled to living in Ottawa.
