From this time onward whaling and trading vessels came in increasing numbers. Very soon a "large colony of beachcombers, escaped convicts, and ship's deserters became established ashore," identified as "chiefly bad characters," according to the log of the Swedish frigate "Eugenie". The first missionary to arrive was Father Louis Désiré Maigret, a Roman Catholic priest. He had sailed from Honolulu on the schooner "Notre Dame de Paix" and began his efforts in December 1837, but he departed on 29 July 1838 for Valparaíso after seven unsuccessful months. In his company were "several Mangarevans and Tahitians," some of whom remained on Pohnpei and left descendants. Ten years later Maigret returned to the Hawaiian kingdom as Bishop of Honolulu. A group of Protestant missionaries from New England established themselves permanently on Pohnpei in 1852. Their letters and journals contain a wealth of information about the island and are preserved at Harvard University.
