Mecklenburg, Mechlenborg, and Mikkelborg is a patrician and historically a prominent family living in Denmark and Norway.
Members include Willum Mecklenburg, Feudal Lord of Eiker, as well as several regional bailiffs, militaries, and privileged merchants.
The name has appeared with various orthography and pronunciation, the most important being Mecklenburg, Mechlenborg, and (in Northern Norway) Mikkelborg.
He traded and exported goods from the royal fiefs (Sleswick and Holsatia), and he had extensive connections to Norway.
Her parents were Carsten Rickertsen, Mayor of Flensburg, and Marina Friis af Arlevad (Arlewatt).
Their third son, Carsten Mechlenborg, remained in Haderslev, where he was a merchant and also the town's mayor.
Customs and export secretary Oluf Carstensen Mechlenborg had two sons: Niels Olufsen Mechlenburg, an estate owner, and Willum Mecklenburg, Feudal Lord of Eiker (one of the last in Norway).
The two brothers' descendants were married into and have descendants in several families of Danish and the Norwegian nobility, among others Werenskiold, von Rømer, de Tonsberg, Huitfeldt, von Hausmann, and the Counts of Wedel-Jarlsberg, as well as in non-noble families like Hansten, Hiorth, and Angell.
As the family no longer were high officials, members began engaging themselves with trade and shipping, then a royal privilege.
