The name Sylvester is a boy's name of English, Latin origin meaning "wood, forest". Sylvester and is often added to lists like Saints' Names For Boys and discussed in our forums with posts like "What would be the perfect twin?".
From the experts:
This name of three early popes has been associated in recent years with a cocky cartoon cat ("Thufferin' thuccatash!") and the Italian Stallion hero of the Rocky and Rambo movies (who was born Michael)--and yet we think it just might be ready to move further back into the mainstream.
Sylvester was at its height in the 1920s, when it was in the Top 200, and hung on in the lower rungs of the ladder until 1994. Lately the name has been most visible as a surname--that of Sue Sylvester on Glee.
