Amazingly, we appear to be distantly related in two ways.
First, you mention Irene Pohl marrying Henry Bang, son of John Bang and "unknown." These are my great-great-grandparents. "Unknown" is actually Ulricke (or Ulrica) Friedrich, born abt. 1853 in Prussia, died 20 October 1932 in Red Wing. John Bang was born abt. 1854 in MO, died 14 April 1941 in Goodhue Co, MN. Their children: Herbert, Loren, Lydia, Rose, William, Clara, and Louisa. Clara was my great-grandmother.
John Bang's parents were Henry (born abt. 1824 in Prussia) and Frederica (born abt. 1837 in Prussia). Their children were John, Otto, Emma, Wesley, Ida, Louisa, Henry, and Sydia (not sure of that spelling).
Our other connection has to do with the name Dahling. My great-grandmother, Clara Bang, married John Henry Bohmbach, and one of his ancestors married a Dahling. For information on that name, and on Frances Pohl and Henry Dahling in particular, go to www.minnesotacousins.com
