Family #33 in the 1798 Grimm census.
1798 Grimm Census 
At some point between 1798 and 1834, Elisabeth Ruhl Waag's two sons with Johann Georg Waag went to live with their uncle and aunt, Christoph and Elisabeth Waag. I searched the Grimm 1834 census, and Elisabeth and her husband's names do not appear anywhere in it.  While it's possible that they moved to another village, it would have been highly unlikely for them to do that without their sons and grandchildren, if any. It's more likely that the couple passed away and their sons, too young to live on their own, went to live with their paternal uncle. In the late 1820s, both men married and were then given households of their own.
