Update on my Franklin county Behn info. My grandmother, Dora Behn, came to the US in 1890. Her father was Henry Behn, brother of Frederick Behn. Their parents were Fredrick Behn and Maria Petzohn, according to an article about Frederick jr in 'History of Franklin County' pg. 484.
Frederick jr. married Dorothea Dreegmuller on 19May1867 and their children were Doras, August, Wilhelm and Rudolph, according to the same article.
Dorothea married William Burmester, August married Emma Meyer, Wilhelm married Avina Meyer and Rudolph married Louise Anna Dohrman.
Any chance these folks may be connected to the Behns you are researching?
