Slavin

Several possible origins:
* Reduced Anglicized form of Irish Ó Sléibhín (“descendant of Sléibhín”), a personal name probably derived from a diminutive of sliabh (“mountain”).
* Borrowed from Yiddish סלאַווין (slavin), a metronymic surname of Slavic origin, ultimately from the Proto-Slavic root *slàva (“glory, fame”).
* English surname from Middle English sclavyne (“pilgrim cloak or mantle”), perhaps a nickname for a pilgrim or for someone who sold such garment.
