Haldemann, Haldimann, frenchised Haldimand,[1] anglicised Haldeman or in variants is a Swiss German surname of Emmental origin,[1] derived from „Halde“ and „Mann“ (literally „heap“ in the sense of side, slope, and „man“; i.e. a man living on a mountainside).
The family name then became established in the 15th and 16th century in the villages and farms of the region (Langnau, Signau, Grosshöchstetten, and Eggiwil).
Some from Walkringen went to the Jura Mountains of Neuchâtel in the 18th century and became citizens of Valangin, Le Locle and Les Brenets.
[1] It is almost impossible to reconstruct a continuous genealogy of the family because of: the frequent repetition of the same forenames, such as Peter, Hans, Ulrich, Christian, used by the various branches of the family over many generations; the gaps in the church records; and the fact that the area in which they lived was an Anabaptist centre at the time of the Reformation (Anabaptist marriages and deaths are not recorded in the church books).
[3] Notable people with the surname Haldemann, Haldimann or Haldimand include: In 1727 three Mennonite brothers (Niklaus, Hans and Michael Haldimann), their wives and children left the canton of Bern and emigrated to Montgomery County, Pennsylvania.
