From a New Land Beckoned By Chester and Ethel Geue page 94.

There is only one with the Fritz spelling that has children.

Fritz, Jacob from Sienscheidermuhle: 5 ; wife and son died New Braunfels July 1846 Arrived on the Harriet in 1845.

There is an umlaut over the u in muhle.

Two Spellings of Fritze are there with an orphan or children.

Have you looked at the death or marrage record to see if parents are listed?

Or do you know where in Germany they are from?
