I just found your post when I Googled my name. I surely didn't remember this site.
About the Wenzels, I have no idea where Jacob Wenzel came from in Europe. I've never been able to find him on a passenger list or his naturalization papers. He did serve in the Civil War in 2nd NY Harris Light Cavalry as a commissary sergeant. He died in 1892 before the 1892 Veterans census was taken. Email me at firstname.lastname@example.org if you want to reply.
My 3rd great grandfather, Conrad Harmon/Herrman, was born in either Bavaria or Baden-Wurttemberg in about 1819 and arrived in America before 1845. I know of no connection with your Hermanns, but I have not been able to even determine when he arrived in the U.S. or who his parents were. If I find that there is a connection, I'll let you know.
My grandmother was a Hirst, born in Mirfield, Yorkshire West Riding, in 1901. I've gone back 6 generation on that branch of Hirsts and have not found any that emigrated to the US. Note that Hirst is a very common surname in that part of England, i.e. around the Huddersfield area.
Neither my wife nor I have any ancestors from Hungary, although we both have GRAF ancestors. Her GRAF ancestors are from Switzerland and mine from Germany with no known prior connections between the two lines.
I do have HERRMANN ancestors who came to America in the mid 1800s from Prussia, mostly from an area in what is now very western Poland.
Thanks for contacting me. The Wenzels in my tree came to America from Hungary (Zsombalya). They were relative late comers, arriving in America in 1909. They are not my direct ancestors; but, are in my tree due to marriage with my father's youngest sister.
Hi Burkely, Gary Naden Here! I don't know about Transylvania, BUT I do know that part of my HERMAN(N) family Lived in BERESINA, BESSARABIA which is now MOLDOVA which at that time was a Part (I Think) of Transylvania! I have my line back to 1558 in Germany. I Do know that under the reign of Catherine the Great in Russia, She contacted her Cousin who was the King of Prussia and suggested that the Steps of the UKRAINE was Fertile farmland and if any Germans wanted to immigrate there they could have free land and maintain their German Citizenship even though they would be living in Russland (Russia) and paying taxes to Catherine, so alot of the HERMANN'S headed that way!!
Johann Jakob Hermann m. Susanna Sofia Geiger. I don't have any dates for them. Their three children: Johann Georg Hermann b. 1785
Sophia Rosina Hermann b. 1792 -- my ancestor; she m. Georg David Blum
Christian Gottlieb Hermann b 1794
Maybe more. All three children were born in Pleidelsheim, Germany, which is near Stuttart. I do not know where the Hermanns came from. I know that there is Balkan ethnicity generally in this line, but I have no idea where it comes from. Most other ancestors on this grandparents' side were in that Baden-Wurttemberg region into the 1500s at least. If you have DNA tested and uploaded to GEDMATCH, we can see if there is any shared DNA. Otherwise, I have no idea about Transylvania.
