Research on the Augustavus Seidel family so far....

  I believe that I have found a place in Germany from which our family came.  That place is Chemnitz, Sachsen, Germany.
Here is how I came to believe this:

My cousin, Robert Chambers, gave me some photos to copy.  He said that my grandma, Pearl, kept them in her purse and gave them to him before she died.  One photo, she told him, was of the “Robert” Seidel after which he and her son, Floyd, were named.  The old family story, which I was told, was when my grandpa’s dad, Gustavus Seidel, died in St. Louis that he was waiting to see his brother from “back East”.  Uncle Floyd, (Robert Floyd Seidel), stated that he was named after his Uncle “Bert” (Robert) who was named after his Uncle.  I didn’t have any for sure connection to the East until the photo.  (There were so many Pennsylvania Seidels with the name Robert.)   The photo front read, “Rockville, CT”.  A letter that Uncle Roy wrote stated that Robert Seidel stayed back east in CT or MA.  It wasn’t until I saw the Census listing in Rockville that I thought that he has to be the Robert.  John Robert Seidel, who went by his middle name (like most in my dad’s family), had “family” names for his children, and was a weaver like Uncle Roy and Gustavus’ eldest sister’s family stated.  So, I’m 99% certain that he is our Robert.   Since I was sent a photo which on the back stated the patriarch of our family was named John Christoph Seidel, John Robert made sense in that he was named for his dad, but went by his middle name. 
In researching John Robert Seidel’s family, I found a 1930 Census record for his 2 daughters.  It stated that their dad was born in Chemnitz, GE and their mom in nearby Pausa, GE.  At the time the Seidel family left Germany, Chemnitz was a cloth/weaving manufacturing city in Saxony.  It all seems to fit with being from Saxony area of Germany and the 2 family lines that mention “weavers”.
So, my belief (80% certain) is that the Seidel family lived in or near Chemnitz, GE, were weavers there and in America, immigrated in 1856 and 1858 (or 1859), lived in Massachusetts and Connecticut until John Christoph died, then moved to Missouri (except for Robert in CT) in 1867 (Agnes, Ida, Mary, and Gustavus), homesteaded leftover RR land (homestead deeds for 3 of them) in Phelps County, MO (except Mary who stayed in St. Louis), and Agnes, Ida, and Gustavus are buried in Roach/Pea Ridge Cemetery in the same plot. 2010

Update: 2011 Found 1865 MA Census showing Agnes and two youngest were in Boston while Robert Seidel and sister (Ida Maier) were in Pittsfield, MA. Agnes was widowed at that time. Also, Agnes' MO Archives death statement states that she was in MO for 17 years before her death in 1885, so she came to live in MO with her family in 1868.
