I've been having fun this morning on the Waseca Co. message board and seeing all the connections I have (besides my LANGE [married Henriette NEUMANN] connections).
Ancestors of the MANTHEY family (through Carl ["Charles"] Ludwig) may be interested to learn that I found his birth-baptism record on the Lobsens film (#245513). The family knew only of his birth 17 Aug 1834, Germany, parents unknown Manthey and Louise ERDMAN.
On the baptism index I found Carl Ludwig born at Osiek (south of Wirsitz city), Wirsitz county, Posen, in 1834 (born ca July/ Aug. based on page numbers) to parents Erdmann MANTHEY and Louise ERDMANN. Unfortunately, the actual baptism is not available for Lobsens records 1821-1840. The index is the next best thing. These parents were married in 1832 when Louise was residing at Radsitz (NE of Wirsitz). If anyone wants more or further details, let me know. I can check for other children or ancestors.
