My Comments notes for Johan Georg Rosemann
After I learned about the Mertz Family of Frankenhausen and that something had been published by Dr. Wendell Mertz on the family, I tried to find what he had written. I couldn’t find it. But I did find a similar — perhaps more comprehensive? — work published by Dr. Wendell’s nephew, Alfred Schafer on this family. Alfred’s mother was Marie Mertz, Wendell’s sister.
In addition to all the various Mertz families covered by Alfred Schafer’s work, I was totally stunned when I found three marriages in Alfred Schafer’s family tree of a male Mertz and a female named Roßmann (hereinafter Rosemann).
Why is this Rosemann connection so interesting? Because the name of the wife of John Henry Mertz was Anna Maria Rosemann. And a Jacob Rosemann was on the same ship as John Henry Mertz in 1737. It is one more piece of evidence tying these Berks County Mertzes (Jost and John Henry) back to their Frankenhausen origins.
The three Mertz-Rosemann marriages:
• Marie Mertz’ mother was Margaret Elisabeth Rosemann (1851-1920). She and Johannes Mertz married 22 Jul 1869.
• Marie Mertz’ great-grandfather was Johan Adam Mertz whose wife was Anna Benigna Rosemann (1779-1841). She and Johan Adam married 12 Oct 1861.
• Marie Mertz’ grandfather was Johan Wilhelm Mertz whose wife was Justine Sophia Gobel. The wife of Justine’s grandfather, George Peter Gobel, was Maria Elisabeth Mertz. And she was the daughter of Johan Nicholas Mertz and his wife Anna Catharine Rosemann.
Like the two Mertz women in Marie Mertz’ tree, the three Rosemann women in Marie’s tree trace their ancestry in different ways but to a common ancestor — in their case to Philips Rosemann who lived 1600-1641 per Alfred Schafer.
Yet, despite all these mentions of the Rosemann family in Alfred Schafer’s book, there was no mention of Anna Maria nor of Jacob, the Rosemanns who apparently emigrated to America.
• Remember Alfred was tracing the ancestry of his mother Marie Mertz. She just happened to be descended from Johan Henrich, father of John Henry and Jost. So those two brothers are only named in passing in his narrative.
• He was not tracing the ancestry of John Henry nor his wife Anna Maria Rosemann.
• He likely had no reason to even know that John Henry married Anna Maria or that she and some of her family had gone to America, he may never have come across that fact.
So I was left with just American records to try to understand the ancestry of Anna Maria Rosemann, wife of John Henry Mertz. And then Dan Goebel came along and told me he was translating and supplementing where possible Dr. Wendell Mertz’ work.
Dan told me that Anna Maria was the daughter of Johann Georg Roßmann (1674-1744) and Anna Sabina Winterstein (1685-1744). He also knew that Anna Maria had a brother Jacob, who I was also familiar with from American records. Jacob was born in 1702, Anna Maria in 1715.
And then I realized that I already knew George Rosemann as the father of Anna Catharina Rosemann who married Johan Nicholas Mertz and also as the great-grandfather of Anna Benigna Rosemann who married Johan Adam Mertz
.
So what is clear is that the Rosemann family of Mertz Church came from the exact same area of Germany as the Mertz family of Mertz Church and the two families obviously knew each other well.
