This type of information interests me, but it probably belongs in the biography. If my family had a connection to Fuller Road in Ann Arbor, for example, I would want to know, but I would expect to find that information in the profile of the person it was named for.
Notables who are namesake to many geographic features would likely just mention the most prominent ones (e.g. George Washington might mention the state and the U.S. capital city but not the hundreds of counties, cities, townships, streets, schools, and more that are named after him). The bio could link to a well sourced list of course.
