This post is about German settlers to Posen. So German names apply to this post.
No, if you had really, really prepared yourself to your own thread you would have known that the Bambers quickly polonized, already in the second generation.
The main driving force behind this state of affairs was the prosaic fact that Bambers were devout Roman Catholics. Ignorance of the Polish language prevented their participation in the spiritual life in their parishes; also being a minority in the Polish territories the knowledge of language was necessary for the proper conduct of their own economy.
The Polonisation of this group was a voluntary act and happened very quickly. The settlers refused to build their own churches, prayed with Poles, and their children learned the Polish language. There were also many mixed marriages with Poles living there. At the end of the 19th century, during the Kulturkampf period, all Catholics in villages inhabited by Bambrzy chose Polish nationality during Prussian and German censuses.
So no, "German names do
NOT apply to this post". You just farted it out.
Secondly, this thread is NOT "about German settlers to Posen", it is about
German settlers to Poznan - or more correctly "Royal City of Poznań", "Regia Urbe Posnani". See post #3, with the translation of the document 1709, originally written in Latin.
The good King Jan III Sobieski, the victor from Vienna, just died few years before (1696) - after reorganizing the administration of HIS ROYAL CITY of POZNAŃ in 1693. Lucky for him, he did not have to face all the tribulations imposed on Poznań by the foreign armies: Saxons, Swedes, Prussians, rebellious Poles, and even Russians. The Great Northern War, The War of Polish Succession, and the Seven Years War had devastating effects on the entire province. But yet, it was still the Poland's Province of Wielkopolska, with its capital Poznań.
But if you are so very eager to call it Posen, you have to wait until 1793 when Prussia authored and participated in the 2nd Poland's Partition - stealing the Greater Poland and renaming it as Prussian Prowinz Posen.
