The name Suckerberg I mean Zuckerberg is so strange. That's just raw german:
Zucker = Sugar Berg = Mountain (or a big hill, but typically it refers to a mountain)
So, a "mountain of sugar" (lots of sugar).
Suckerberg kind of fits better, since "sucker" is not german (berg still is of course; I think scandinavian countries also have berg, though that could be burg, aka castle). Plus, Suckerberg describes the evil behaviour of Facebook better. The USA really has a problem with its billionaires.
Not strange. It's a Jewish name.
[resource]+[mountain/stone/field/valley/tree] in German is a very common pattern for Jewish surnames. A quirk of how surnames were adopted in German-speaking regions in the 18th century
Sugar mountain at least makes sense, unlike e.g. wine stone
