August Tessmer (tesmer) is my 2nd ggf.We don't know much about his side of the family.We do believe he was born somewhere (and lived) in Prussia.He married Amelia Kalk we believe in Minnesota and know they lived in Minnesota. They had at least five children, Fred, Leo, Augusta, Amelia (sp.), and then my relative Charles, who farmed by Beardsley, Minnesota with his wife Minnie Rieman (sp.). I have found a headstone with the name Amelia Tessmer (Dec. 4, 1850 - Sept. 19, 1927) near Rockford, MN and this matches possible dates for his wife's life. Please send any information that can help.
