This happened over the weekend in Italy and I want to see if anyone else can think of another case in any other league:
Two players with the same last name playing on opposing teams and scoring in the game.
Example: In Ascoli-Sampdoria this past weekend, Marco Delvecchio scored for Ascoli, while Gennaro Delvecchio (no relation) scored for Sampdoria. The score was 1-1.
