I'm not related, but can provide you some information about your elusive Mrs. Casper (Ackermann) Kirchbaum.
Per the Grant Co. WI marriage records:
Caspar Kirschbaum married Elizabeth Ackermann, 30 Jun 1859. Recorded in Book 3, Pg. 26. Caspar is recorded as the son of Riner and Katherine (Unknown) Kirschbaum. Elizabeth the daughter of Peter and Medlin (Unknown) Ackermann.
Another marriage of Christiana Kirschbaum lists her parents as Reynard and Catherine (Moeller) Kirschbaum. This would appear to be Caspar's parents as well.
Hope this adds at least another name to your tree.
