A Potential Genealogy for Reitz, beyond 1100
I enjoy studying up on genealogy, in my spare time. My relatives have prepared a well–documented, hand-prepared database (gedcom) of ~6,000 people (mostly Reitz plus Jodon/Jaudon) going back to the 1600s, in Hessen, Germany. The surname (paternal line) stopped, however, at a man mysteriously named “Johannes of Röhig” (~1640).
Convention over Configuration
It turns out, Germans had a very strict naming convention that they used for naming they children, during this time period. Some families with German ancestry use remnants of this to this day, but it’s very rarely seen in action quite like it was then. The convention is as follows:
1st Daughter after the Mother's Mother
2nd Daughter after the Father's Mother
3rd Daughter after the Mother
4th Daughter after the Father's Father's Mother
5th Daughter after the Mother's Father's Mother
6th Daughter after the Father's Mother's Mother
7th Daughter after the Mother's Mother's Mother
1st Son after the Father's Father
2nd Son after the Mother's Father
3rd Son after the Father
4th Son after the Father's Father's Father
5th Son after the Mother's Father's Father
6th Son after the Father's Mother's Father
7th Son after the Mother's Mother's Father
Origins of the Surname Reitz, Reitzenstein, and Van Der Grün:
I took that information, and took this database a bit further — “Johannes of Röhig”, I turned into “Joh. Georg Lenhardt Reitz”, born in 1648 in Röhig, Germany — the potential full name of the father of our entire family.
Then, I took the naming convention (which appears to have been in full–swing, at the time), and kept going backwards.
Using the naming conventions, I determined that Joh. Georg Lenhardt was fathered by:
Peter Reitz, 1630
Georg Reitz, 1600
Georg Reitz, 1557
Hanß Reitz, 1525
Jacob Reitz, 1500
Then, I used the collaborative environment provided by the Latter Day Staints and FamilySearch.com, as well as their automated tooling, &c, to derive a jump — that Reitz was a shortened form of Reitzenstein. The paternal line continues:
George von Reitzenstein, 1482
Hans von Reitzenstein, 1430
Thomas von Reitzenstein, 1414
Thomas von Reitzenstein II, 1383
Thomas von Reitzenstein I (unknown)
Konrad von der Grün II, 1295
Heinrich von der Grün, ~1280
Konrad von der Grün, 1250
Johan von der Grün, 1246
Eberhard von Berg, 1098
Adolfph III of Berg, 1080
Adolf II Altena, ~1040
Going Further Back
According to Wikipedia, Reitzenstein was a German dynasty of Franconian knights.
