I've done some digging into federico gualdi as a bit of fun.

- Gualdo is his family name from Elio Galdo, this fits the old german waldo personal name. Its origin in german, this family that settled in swabia.
- galdo gualdi have a German connection as italinazied walther
- This family had influence over the church in 1200s. This explains why federico was able to stop the inquisition centuries later. His family name had weight.
- Born around 1250 ? took fathers name ?
- Titian painted federico more than once. Several young men he paints resemble the portrait attributed to gualdi
