8371 Goven           Discovered 1991 Oct. 2 by C. P. de Saint-Aignan at Palomar.
The village of Goven in Brittany is the home of the Bernardinis, who were an extraordinary host family for the discoverer during his year-long stay there. Jean-Paul Bernardini served as a navigator in the French Marine during the 1960s, frequently practising the dying art of celestial navigation.
