From an English surname which was derived from the Old Norse given name Þórsteinn (see TORSTEN). The name was popularized by the actor Dustin Hoffman (1937-), who was apparently named after the earlier silent movie star Dustin Farnum (1874-1929).
From the Old Norse name Þórsteinn, which meant "Thor's stone" from the name of the Norse god Þórr (see THOR) combined with steinn "stone".
Guys, I know a Dustin that is a wonderful, caring, awesome, fantastic, and loving person. Just because there was a Dustin that treated you like that, doesn’t mean all of them are bad. I could go on for hours of how good of a person he is. He’s the complete opposite. I feel bad for all the other Dustin’s that are reading all the bad things.
