Agnesia married Jacob Casper Waldhauer on June 27, 1758, in Effingham County, Georgia. I have seven children listed for them: Margaret (1759-1841), Lydia (1760-1762), Elizabeth (1763-1842), George (1764-1766), Hannah (1767-1846), John Casper (1768-1830, my 4th great grandfather and husband of Mary Floerl and father of Elizabeth Waldhauer), and Salome (1780-1857).

I attempted to do some additional research into Agnesia in the Salzburger/Georgia Germans books in the genealogy room at my local library, but the records were confusing since her mother has the same name. I had that she was born in Germany, but I removed that since I couldn't find any information to confirm when her parents came to Georgia or where Agnesia was born. More research will need to be done.
