Our Hoover line is now known

 After meeting with my Hoover Y-DNA match and his daughter, who is a professional genealogist, I can now say with certainty that our Jacobs line is connected to that of Johann Michael Huber, b.1737 in Lancaster Co., PA, d. 1816, Dauphin Co., PA. Their research had also led to Johann Michael Huber, though she had some residual uncertainty; that uncertainty was erased by the Y-DNA data and the autosomal DNA data that I presented to her. 

The Y-DNA data shows a four-marker difference on a 111-marker comparison of her father's data to our Jacobs line; this result puts the median time to most-recent-common ancestor (MRCA) at 1706, right in the ballpark of the expected birth year of our John Jacobs (b.1731/32). This would suggest that, most likely, our John was a brother or first-cousin to Johann Michael Huber. 

PA Mennonite records show the father of Johann Michael Huber to be Hans Jerg Huber; Hans Jerg is buried in the same Spring Hill "Huber cemetery" that Johann Michael Huber is buried in. Researchers have Hans Jerg Huber, also recorded as Hans George Huber, as born in 1691. Jerg is equivalent to Georg/George in German, but is usually written Jorg. Those researchers also have his wife in America as Anna  Maria Hoos, who he married in Blankenloch, Baden-Wurttemberg, Germany (just north of Karlsruhe) 11 Aug 1733 before immigrating; she is recorded as the third wife of Hans Jerg Huber. There seems to be little controversy over this research, however I plan to do my own validation of it. I have found the website of a Kris Hocker , who has done in depth research on our Huber line, and am attempting to get in contact with him.

It is very important that we understand, if possible, whether Hans Jerg Huber had any brothers who immigrated to America before 1743. If he did not, then our John was likely a brother of Johann Michael Huber, born to the second wife of Hans Jerg.

There is research claiming a pedigree for Hans Jerg that continues in Germany, though I don't want to get into that at this time; I want to validate what is available on Hans Jerg first. Most likely his pedigree eventually goes back to Switzerland, known to be the origin of most Huber's. 

Y-DNA alone would have eventually led to this conclusion. The autosomal DNA alone would have certainly strongly suggested it, but there would have been some significant residual uncertainty (paternal vs. maternal line). The combination of Y-DNA and autosomal DNA, along with the stories from the Chester Historical Society's "History of Chester, Vt" and the History of Rutland County, Vt., leave no doubt that our Jacobs line originally came from Germany as Huber's.
