My great-great grandfather was John Baumgartner. He was born in 1826 in Germany and died in Minnesota in 1909. His wife's name was Elisabeth. She was born in 1819 in Switzerland and died in Minnesota in 1899. I do not know her maiden name.
Their daughter, Elizabeth, born in 1850, married Melchior Kienholz.
I have been unable to find any other information on John and Elisabeth's ancestors. If anyone has any additional information, please let me know.
