The family ENTZ (Ens) probably comes from East Friesland. In East Friesland the name Enno or Enne is rather usual. Under the Mennonites of the early 17th century there is Enne Dyrks, Enne Ribs. In the East Frisian Mennonite community Neustadt-Gödens nearby Wilhelmshaven the name Enno appears more frequent as first name. According to the Frisian patronymic naming the name is also inflected as a surname used weakly, like the form "of the boy". The Mennonites were called there not Ennes or Ens, but Ennen. In 1734 the Mennonite Jacob Ennen died in Neustadt-Gödens, another was called Albert Ennen, the third Gerrit Ennen. The municipality which experienced their biggest blossom in the 17th century, has surely delivered some emigrants to West Prussia. But also the strongly inflected form by the name of Enno appears in East Friesland like we will see below. The name has an strange effect if strong and weak flection are used together. So there is in the consignment of 1776 a shopkeeper and a Mennonite dressmaker in Marienburg which lead the name En-s-en. To the strong form Ens an "en" was suffixed. Perhaps they or their ancestors have immigrated from the provincial town Neustadt-Gödens to Marienburg. We found 1654 in Orloff the strongly inflected form Hans Ensz (Ens zoon). Around 1610 Jan Ents from Veenhuisen is named in East Friesland (near to the estuary of Ems). He was a representative of the so-called "Hard Frisians ". Further on also in West Prussia the name was written with "t". In 1709 Anke Entzen was buried in Orloff. In 1701 Jacob Entz on Tiegerweide is named. 16 "Entz" families which are known in 1727 between the Vistula and Nogat, all were written with "tz". In the consignment of 1776 all representatives of this family registered like this: Ens.
