Jonas Hummels (born 5 August 1990) is a German retired footballer who played as a central defender for SpVgg Unterhaching. He is the younger brother of German international Mats Hummels, and the son of Hermann Hummels, a former footballer and manager.
Jonas has the same last name as his father and brother.
The model probably got confused because I used different keywords not found in the text like "last name."
