Where the Grasso surname comes from
Grasso, “fat,” comes from a nickname that was once almost a compliment. When hunger was a constant guest and meat was eaten only a few times a year, a fat man was sturdy, well fed, healthy. Someone who was doing well. Then the nickname passed from the founder to his children and grandchildren, who may well have been skinny.
The surname is old: a Landolfo Grasso appears in Milan as early as 1191. A nickname this simple could be born anywhere, and in fact it was born in many different places.
A pirate and an actor
At the end of the 12th century a Grasso who had left Genoa as a merchant ended up leading a fleet and governing a Mediterranean island. Seven centuries later, a Grasso who grew up among the puppets of Catania performed in Moscow and New York. The great masters of the theater never forgot him. Their stories are in the PDF.
