In the realm of Muggles, a person with the last name Potter is a potter. The Potter family has had two representatives on the Wizengamot: Henry Potter (also known as Harry to his close friends), who was a direct descendant of Hardwin and Iolanthe and served from 1913 to 1921, and Ralston Potter, who served from 1612 to 1652 and was a staunch supporter of the Statute of Secrecy (in contrast to more militant members who wanted to declare war on the Muggles).
