Vaughan comes from a formal Welsh name for small or younger (as in son, to distinguish from the father) ‘Bychan’ (or ‘Fychan’ when mutated) This over time sometimes became Vychan whilst the ‘ch’ sound caused some problems for some and changed in some cases to a softer ‘gh’ sound, as in Vaughan. This often developed into Vawn, Vane, Bawn, Baughan and the phonetic Welsh Fôn. Bearers of the name Vaughan sometimes choose to revert back to the original Fychan or Fôn.
