Reimer is a Mennonite family name that probably originated in the Netherlands and was brought to West Prussia by religious refugees. At any rate, members of the Reimer family took part in the reclaiming of the land north of Tiegenhof in the great Marienburg Werder.

In 1626 Michel Reimer is mentioned in Glabitsch north of the Vistula at Elbing. Two decades later he became a councilor of this village, an area that had just emerged from the fresh-water lake about 1600. In the neighboring Poppau, Isebrandt Reimer took part in the draining of this land which is below sea level. The Reimers were also active settlers in the Scharpau. Franz Reimer on the "Polish Hube" passed his land on to a Wiens about 1640, and Wilm Reimer was living on the Schröderskampe near Altebabke ca. 1650. Johann Reimer was one of the founders of the village called Reinland, whose lands did not become arable until 1725.

Over the course of several centuries the Reimers in the Werder moved to the south. In 1936 there were 14 Reimers in the Fürstenwerder congregation, 5 in Tiegenhagen, 28 in Ladekopp, 18 in Rosenort, 76 in Heubuden, 15 in the Danzig congregation, 1 in Elbing-Ellerwald, 2 in Thiensdorf-Preussisch Rosengart, 5 in Tragheimerweide, and 1 in the Ludwigshafen congregation in the Palatinate. This makes a total of 165. There were also Reimers among the West Prussian Mennonites who chose to immigrate to Russia. Gustav Reimer (1884-1955), a deacon in the Heubuden congregation, was prominent figure in the West Prussian Conference; he moved to Uruguay in 1950.
