John,
I am working on my family tree and we have the same Great Grandmother and Grandfather. Dorthea was my 3rd Great Grandmother on my mothers side. I have limited information on her and her husband Joachim Woehlert. I do know that her parents were Lewis Froh and Elizabeth Schief, but past that I have hit a dead end.
I know that Joachim and Dorthea had 9 children; John, Sophia, Henry, William, Louisa, Bertha, Anna, Charles and Netti. I am directly related to John. He married Willhemina Teltow and had 9 children; Edna (my great grandmother), Edmund and Eva. Edna married Julius Luetzow and had 4 children; Victor, Gertrude, Earl and Willard. Earl is my grand father.

If you have any birth dates or any related information on the family I would love to coorespond with you to see how much more we can fill in on our family trees.
