This morning, we visited the Diakonnisenkrankenhaus in Dresden. It's a hospital for a deaconry. In Lutheranism, it's akin to an order of nuns. It was founded in about 1842, and one of the original founders was a lady called Ida Thode, who was the sister of our great-great-great-grandmother, Luise Friedericke Duncker. Ida's maiden name was Rautenberg; she married Eduard Thode.
After our visit to the Diakonnisenkrankenhaus, we stopped by the banks of the river Elbe at Villa Rosa, which was the former address of our great-great-great-grandfather, Gerhard Friedrich Thode, husband of abovementioned Luise Friedericke Duncker. The house he lived in back then no longer exists. The villa was designed by Semper, who also designed Dresden's famous opera house.
The Trinitatisfriedhof is a few streets long, and we spent at least 45 minutes searching among the graves for our ancestor. Christine was previously told the book containing information about people buried around that time was destroyed in a fire. We asked again at the office after our search and we were told the same thing - but it didn't hurt to try.
