The Wends with the surname Swore lived in the Kingdom of Saxony. German was the official language of the Kingdom just as English is the official language in Australia. All places in Saxony were given a German name. So even today when one drives into a village, town or city in the Wendish areas there are two names displayed—both the Wendish and the German. The street names are given in both languages. In Australia one can sometimes see the ancient aboriginal name displayed as well as the English name. eg. ‘Uluru’ is the indigenous name, and Ayers Rock is the English form.
In the Kingdom of Saxony everyone had to have a German surname for official and legal use. Sometimes the German form had no relation to the Wendish form, just as the English name ‘Ayers Rock’ has no connection to the indigenous meaning of the name ‘Uluru’.
The German form of the Wendish surname ‘Swore’ was usually Zwahr, or Zwar.

In Germany both forms are still used today, sometimes within the same branch of a family. The descendants of the Wendish ’Swore’ family from Drehsa who remained in Germany seem to have always spelt the surname as Zwahr down to the present time.

The International Genealogical Index of the Church of Jesus Christ of Latter-day Saints lists a Peter Zwor who was born in Binnewitz near Bautzen in Saxony on 28.9.1788. His father’s name is given as ‘Johann Peter Swora’. It is a good example of the father using the Wendish form of the name and the son a German form.

When the Wend Peter Swore migrated to Australia in 1854 his name is given at the top of the official Saxon passport as ‘Peter Zwar’, but at the bottom of the same page he signs his name as ‘Peter Zwahr’.
