I show the marriage as 26 Oct 1877.
Louis born 20 Oct 1855, dies 30 Apr 1922 in Appleton (East of Greenville).
Louis is the son of Johann Carl Christopher Pinger and Hanna Elisabeth Dorothea Zachow both from Domsuhl, Crivitz, Mecklenburg-Schwerin (17 Jun 1842 Marriage...ELEVEN Children).
GEDCOM available. I'd love to know where Maria Lubben/Luebben comes from. (I'll look at the next post as well!).
