Hello, I have a Family Group Record from a Mr. Hensel. He writes that the parents of these possible siblings of Tirschtiegel, Kreis Meseritz in Posen (also could include Neumark in East Brandenburg) were Franciscus Gasparvis DOBKOWITZ and his wife Marianna DREWNIAK (also has a forum here).
Joseph DOBKOWITZ is buried at the Trinity Lutheran Church in Dodge County Nebraska.
Veronica Marianna (Dobkowitz) WEIMANN is buried at St. Leo's Cemetery in Snyder, Nebraska with her husband, "Karl Carolus WEIMANN" that I see written before me.
perhaps this is their daughter (?) Martha Weimann 31 July 1862 - 14 Nov. 1908
This is found on the "Catholic parish register of Tirschtiegel, Posen, Germany film numbers 1417878-1417886"
Perhaps this will help someone and more information will follow. Amy Uehara, (This is not my direct line. It comes via the elder brother of my great-grandfather. The elder brother, Constantine KLEMKE, married the daughter of Joseph DOBKOWITZ, Martha Margaretha DOBKOWITZ 27 Dec. 1866- 22 Feb. 1956)
