It was at the request of the Archbishop of Port-au-Prince that the Montfortian missionaries founded their first Institution outside France, in Haiti, on 30 August 1871.

The laws voted in France against the religious Congregations in the 1880s forced them to go to Holland and Canada in 1883 (from where they would leave for the United States in 1903).

At the beginning of the 20th century, for similar reasons, they went to Malawi (1901), Denmark (1901), Iceland which was then a Danish territory (1903), Belgium (1903) and Colombia (1904). On 1st January 1905, the first three Provinces of the Company of Mary were created: France, Canada (along with the United States, which became a Vice-Province in 1948) and the North which, included Holland and Belgium.

The first house in England was started in 1910 and in Italy in 1919 (without counting the Procurator General’s office set up in Rome in 1900).

Then new countries: Mozambique (1922), Madagascar (1933), the Democratic Republic of the Congo (1933), Indonesia (1938).

The years that followed the Second World War saw a growth in membership which facilitated successive arrivals in Germany (1952), Spain (1953), Portugal (1956), Papua New Guinea (1958), Peru (1961), Brazil (1965), Argentina (1966) and Ireland (1966).

Latest countries: India (1973), Uganda (1973), Nicaragua (1974), Equator (1982), Philippines (1984), Kenya (1991).

It was only from 1960 that a second wave of Provinces emerged: in 1960, the Province of Great Britain and Ireland; in 1961, the Provinces of USA and Colombia; in 1966, those of Belgium and Holland (division of the Province of North); in 1969 the Province of Haiti; in 1979, that of Germany.

The other countries are delegations. In 1998, five delegations were attached to the Central Administration: Madagascar, Portugal, India, the Philippines and Africa­ Formation (made with the aim of forming the candidates from Malawi, Zaire, Uganda and Kenya); The other countries (Argentina, Spain, etc.) are attached to Provinces (ex. Peru to Italy).
