My wife's maiden name is Wythe, pronounced "Why-th", family origins in England about 1560. The family name changed to Wyeth (as in Joshua Wyeth of the Boston Tea Party, and Andrew Wyeth the painter) and then back to the original spelling of Wythe over about 100 years as the family migrated from Cambridge, Mass. to Pennsylvania (the Luzerne valley) , West Virginia, (Licking Co.) Ohio, and then Vigo county Indiana. The old English spelling of the word "with" was wythe, hence most people, especially Southerners, are convinced that the name of the town of Wytheville should be pronounced "With" ville. It's really absurd when anyone, not a Wythe, tries to tell my wife that she is mispronouncing her own maiden name! ;^)
I found the name Wythe spelled as With, Withe, Wythe, Wyeth, and other variants in England. This is normal considering many people could not read or write. The census taker had to phonetically guess the closet spelling based on the sound of the last name. Also, if the family, in England, had peerage, they would pay more in taxes so they would change the spelling of their last name....I am not making this up!
I have seen baby name list where they attribute the name Wythe, meaning "courageous"....they are truly ignorant, that's just something they made up. It's a family surname that has been used for hundreds of years to denote descendants of the Wythe/Wyeth family, which daughters would name their sons using their maiden name as the son's first name.I see that your first name is Wythe, are you a descendant of the Wythe/Wyeth clan?
