cherrybim: Shepsel is a nickname for shabsi, a name originally given to a boy born on Shabbos. Nothing to do with sheep.
Wolf: The name Ber, as in Yissochor Ber, has nothing to do with a bear. It’s in honor of the ?????? which reuven picked for his mother so she should conceive and she gave birth to Yissachar. In German-Yiddish this plant was called “berelach”, probably related to berries. Eventually Ber was separated from Yissochor (perhaps when there was a living grandparent named Yissochor). Its original meaning long forgotten, Dov was added to make it into a Hebrew name, so it would be proper for aliyah l’torah.
