In Catholic tradition, patron saints are holy men and women whose lives and intercession are considered especially suited to particular needs, groups, or situations. The Church's practice of invoking saints reflects the doctrine of the Communion of Saints — the belief that the faithful departed remain united with the living in the one Body of Christ and can intercede before God on our behalf.
The designation of a patron saint for "Large Families" reflects centuries of Catholic popular devotion and, in many cases, formal proclamations by popes or bishops recognizing a saint's particular connection to this intention through the circumstances of their life, death, or documented miracles.

Saint Margaret of Scotland is invoked as patron of large families. Margaret was born around 1045 in Hungary, where her father Edward the Exile, of the Anglo-Saxon royal house of Wessex, was living in refuge from the Danish conquest of England. The family returned to England in 1057, but her father died on arrival; following the Norman Conquest of 1066, Margaret, her mother, and her siblings fled north and were received at the court of King Malcolm III of Scotland, whom she married around 1070.As Queen of Scots she set herself to the reform of both the Scottish court and the Scottish Church.
