The origin is probably in one of the still unassigned early Thuringian Lines
lie. It is still uncertain whether the branch originated in the Mecklenburg stem line
or from the Franconian line
Has. A link with the Hartung Lorber mentioned in 1401 in Naumburg seems conceivable due to the spatial proximity. My guess is that Mecklenburg roots and connections to the important cloth traders in Stralsund at the beginning of the 16th century are somewhat more likely than connections to Franconia. This suggests that the Rastenbergs were listed as master tailors in the 17th century. A profession that does not seem to occur with the Franks of that time and would go well with cloth traders.
Probable progenitor
Hans Lorber ( between 1551 and 1555), 1514 Mayor of Rastenberg in Thuringia, earliest known Lorber in Rastenberg. Origin unclear.
Werdegang
The Lorbers belonged to the upper class of the town of Rastenberg in Thuringia. From the 16th to the 18th century, several members were mentioned as mayors. They made their living as master tailors, linen weavers, oil millers and carpenters.
Johann Gottfried Lorber (1702-1755), sergeant in Weimar;

Benjamin Enoch Nikolaus Lorber (1720-1781), pharmacist in Prenzlau;
Johann Christoph Lorber (1776-1837), gravedigger and field protection
Spread today
Bis heute leben viele Lorber in Thüringen und anderen Regionen Deutschlands, die sich auf die Rastenberger zurückführen können. Auch Nachfahren der abgezweigten Familien sind heute in Mitteldeutschland, Wien
und Russland
zu finden - auf diese wird jedoch noch gesondert eingegangen.
