I'm not sure if these'll be any help - likely too far back (by a couple centuries!), too far afield (Saxony, near the Czech Republic), and just a similarity of names (no "K"):
Maria Nitzsche (1611-1688), daughter of Matthes Nitzsche and Anna ____: married Johannes Schumann (1616-1678) on 10/11/1640 in Reinhardtsgrimma.
Anna NItzsche (died 1620), daughter of Erasmus Nitzsche, and widow of Andreas Schreier (born ~1555, died before 1605): married Franz Brehm (1584-1621) on 6/10/1605 in Schneeberg.
