I have Harmon 1882-1950 son of Johan Friedrich Parman 1858-1889 and Sophia Qualman 1859-1934. Johan is the son of Joachim Christoph Pohrmann/Parman 1828-1912 and Caroline Christina Frederika Wolter 1833-1878. Joachim is the son of Johan Christian Pohrmann and Marie Sophia Gilow who were married 10/20/1826 in Kittendorf, Mecklenburg, Germany.
I also have Luella 1895-1995 as the daughter of John Christian Parman 1859-1940 and Mary Mentall 1863-1947. John Christian is the son of Johann Christian Pohrmann 1828-1900 and Johanna Maren 1832-1927. Johann Christian is the twin brother of Joachim Christoph, both born Oct 1827.
Thus, Harmon and Luella were second cousins. You can verify their marriage through http://search.labs.familysearch.org/recordsearch/http://search.labs.familysearch.org/recordsearch/ they were married in Monroe, Michigan 23 Feb 1915. Harmon is listed as Herman however. I do show Harmon as being married previously to Lena Ohm 1884-1912 and his first three children were with her. I do not show a previous marriage for Luella.
I am descended thru Joachim and have more family members if you are interested.
