My first name, Perry, is from the Welsh phrase "ab herry," son of Henry. I was given this name in honor of my great-great-grandfather, Perry Julian Castlebury, who owned the first car dealership in Aiken, South Carolina and was rich during the Great Depression.
My middle name, Hamner, is a corruption of the name Hanmer, which either means "of Hanmer," a diocese of St. Asaph, or "born near Hanamere Lake."
My last name, Watson, means "son of Watt," which is a nickname given to people by the name of "Walter." However, I choose to believe I am actually descended from the super-awesome Scottish engineer James Watt, for whom the unit of power is named and who perfected the steam engine, effectively kicking off the Industrial Revolution.
Also, my Latin name (given to me by my awesome Latin teacher) is Maximus, which means "the biggest" or "the greatest," or both, in my case.
