Reaver is an uncommon given name of unknown origin, possibly derived from Old English 'rēafian', meaning 'to seize or plunder'. It has been used sparsely throughout history, perhaps most notably by American author and journalist Hunter S. Thompson's character Raoul Duke in his book Fear and Loathing in Las Vegas. The name Reaver is often associated with strength, power, and resilience due to its etymology and the characters who have borne it.
"Reaver saw its highest popularity with 8 births recorded twice, once in 1921 and again in 1923. Its lowest point was a single year with just five births each in 1919 and 1930. Over the span of these years, there were a total of 38 children named Reaver."
