As you can see, there were many more children than my grandmother had told me. It makes sense that she was aware of the younger children. She was born in 1899, so the four older children (if they survived this long) were likely grown and on their own by the time she was old enough to know them.
I descend from Charles' sister Emma - so that makes us distant cousins! I haven't yet been able to trace this Tesche family back to Germany - but according to my grandmother her parents came from the Black Forest area (Baden-Wurttemburg) and the Alsace. I'm still not positive which line (Tesche and Zimmermann) came from which location. The 1880 census for Charles A. Tesche and family (which shows some of the older daughters - Emma, Clara and Julia) indicates that Charles was born in Prussia.
I love to have someone else help me with this family! I'll be happy to share what I have. It may be easier if you contact me off-board at firstname.lastname@example.org
