Koberstein Surname migration around the world

Hypothesis of the Koberstein Surname Migration

within Europe and

known emmigration out of Europe

This is a tree chart of the earliest years of Koberstein records in major states/areas.  The branches among the German states and European areas show the most probable location they came from, however, this is not proven.  The branches of the emmigration out of Europe is well documented.  It seems very probable that the earliest Koberstein's in the Rhineland-Pfalz area  (along the Rhine River and its tributary the Mosel River that joins the Rhine at Koblenz) moved up the Rhine river first toward Baden-Wurtemburg then secondly to the northern part of Bavaria on the Mainz tributary.  During this migration, Koberstein's started showing up in Landsburg/Warthe area.  This may have been a movement of the Koberner Knights to help settle this area and into Poland.  When we see the first Koberstein records in Berlin it also starts to appear in other areas such as Nordrhine-Westfalen and Sachsen-Anhalt.  Meanwhile the Koberstein's in Landsburg move into Czarnikow, West Prussia, other parts of Poland including the Chelm area which is very near the Volhynia (now Ukraine) area.  The earliest Berlin addressbuch entry is 1820 but the Berlin branch in this tree chart covers all major areas of the former Prussia.  Industrial centers like Berlin started to cause migration from rural areas to the cities at about this era.  Here is an article on this Urbanization process and one specifically about Germany.  So Berlin probably drew from all the surrounding rural areas, thus the connnecting line in the chart.  I also have 14 Koberstein families that emmigrated out of Germany/Prussia, Poland and Ukraine.  This is a good article talking about the emmigration out of Germany.  This article talks primarily abou the "Palatine" emigration of which the emigration of Hans (2 in the chart key below) about 1750 (the peak of this emigration) is a good example.  This Koberstein family changed their Surname to Coverston(e).  Here is a good article on emigration from Germany (Prussia) in the 19th and 20th centuries, of which the other Koberstein emmigration is typical.  It indicates that 1854 was the peak of this emmigration to America, of which the emmigration of the Ludwig Koberstein family from West Prussia in 1854 to the homestead land of Wisconsin is typical. Like so many they kept on moving first to Minnesota and then some on to Oregon.  See the key in the tree chart below for the destination American states or countires that they emmigrated to.  Also, "The short-term rise of transatlantic migration in the early 1920s peaking in the year of inflation in 1923 was above all determined by the results of World War One." speaks to the smaller group of immigrant Koberstein's at this time.

The circle of German Koberstein migration

This map illustrates the appearance of the earliest Koberstein birth dates in city-areas within modern Germany.  The lines connect them by year but they are not meant to show movement just chronology.

Here is a chart of the actual or estimated birth date of the earliest Koberstein in each of the areas along the circle starting in the Rhineland in western modern day Germany.  This list is sorted by birth year.

*     This is the family that immigrated to Indiana
**   This is the family that immigrated to Wisconsin then to Oregon.
*** This is the family that immigrated to Wisconsin

This is a little contrived, a pattern is most clear from Rhineland, Baden, Unterfranken county in Bayern, Saxony, to Berlin.  The jump to Nord-Rhine may not really fit as in the 1800’s there was probably a more widespread migration not following simple trends.

Now as you explore the earliest birth Koberstein’s by area in the Prussia/Germany area you notice an interesting phenomena. The above list of area’s by earliest birth date form a circle around the state, Hessen, leaving out all of the Northern most states. There is jumping back and forth in similar time periods but the overall trend is unmistakable. However, as you look at the eastern Kreis of the Brandenburg area and the Prussian states of Posen they are much earlier than the Berlin area, in fact the earliest are more like the birth dates for those in the Rhineland-Pfalz/Baden-Wurtemburg areas. The trend of migration is from Brandenburg to Posen, West Prussia, Poland, Ukraine. Here is a map of the appearance of the earliest Koberstein birth dates in city-areas within Poland.

Here is the list of that progression.

Area	Name	Earliest Birth Year
Landsburg, Brandenburg	First name not given	1579
Sternburg, Brandenburg	Christoph	1600
Schwerin,Posen	Mertin	1637
Czarnkow	Matys	1671
Belsin	Christoph	1748
Ksawerow, Leczyca, Lodz, Poland	Peter Kaminski	1754
ColonieBrinsk,Strasburg,WestPrussia	Christoph	1775

From this analysis I have constructed a chart that illustrates this situation:

Koberstein Surname population growth concepts

Here is a real intersting article on Surname growth mathamatics.

More simiply you can derive these growth curves for various assumptions.

Surname growth curves.

#	1	2	3	4
1	1	4	9	64
2	1	8	27	256
3	1	16	81	1,024
4	1	32	243	4,096
5	1	64	729	16,384
6	1	128	2,187	65,536

* The vertical  left numbers are the generation number beyond the parents

The horizontal top numbers are the number of surviving males that become parents.

Of course these numbers all double if the wife takes on the Surname of the husband,

which is the general tradition in western civilization.

This all assumes that each generation has the same number of male offspring that reproduce also.



Here are these growth curves:

In the modern era of two children per family the Surname would eventually become extinct (see the article for the statistically valid derivation of this).  An interesting deduction can be made that those populations that have only 2 births per family will have the Surname go extinct, but those that have larger birth rates the Surnames will increase.

In the 1800's and 1900's it was not uncommon to have 6-8 children, which is 3-4 males of which I will guess 2 might survive to reproduction.  This would put you on the relativly modest Surname growth curve of only 128 (254 with wives) in 6 generations.  I always assume a generation for marriage age to be about 20 years on the average, so this  is 120 years.  So over the 500 years (25 generations) from 1500 to 2000 that will be 3,554,432.  That is clearly not the case, in fact based on my research I would guess there are at most a few thousand Koberstein surnames in the world today, so these assumptions must be drastically reduced.
