I show Anna Bartke (also Bertke) marrying John Borgmeyer in 1876 in St. Clair, IL. This was a second marriage for both. Her sons Bernard Bartke and Gerhard Bartke (b 1864 and 1866) are in their household in 1880 along with Borgmeyer's children Marie, Theodore, Stephen, and Edward J, b 1863-1874.
I think John Borgmeyer's first wife was Angelia Surmeier. I have a little more information on this family.
