The lineage begins with Olof, whose son, bailiff by profession of the village of Pepot near the town of Porvoo in Finland, is mentioned until 1489. Johann Månsson Ållongren, († 1651), sixth generation descendant of the founding father, was incorporated in 1625 in Finnish knighthood. Initially, the genus was considered extinct in 1806. It later turned out that after the Peace of Åbo in 1743, through the ceding of land by Finland to Russia, a branch of the family had ended up on the Russian side of the then split Finland. A scion moved to Russia in the mid-nineteenth century. He spelled the family name from then on as "Ollongren", just like his descendants.  The next generation moved to France after the Russian Revolution. Alexander Ollongren (1901-1989), born in Kiev, worked between 1920 and 1932 on Java and Sumatra in the Dutch East Indies; he became a Dutch citizen in 1933. His son, also named Alexander (1928) and his descendants were incorporated into the Dutch nobility with the predicate jonkheer / damsel, merging into the male line.  In 2018, the presumed successor as chef de famille - he and his father are the only two surviving male descendants of the family - only has two daughters, which means that both the Finnish and Dutch noble family are at risk of extinction.
