There is debate as to which surname is correct for Wilmuth, Redd or Redmond. There is no hard evidence of either name. The middle name of their eldest son John is a strong clue but it too has been listed as Redmond in some charts and Redd could be a shortening of Redmond. According to Charles Cabiac (credits 18) he believes that "Wilmuth's surname was Redd (not Redmond) based on the fact that the Medarises lived in the northern part of Guilford Co., NC, near the Rockingham Co. line. The Redd family was an important pioneer family in that area, and there is a John Redd Boulevard just across the state line in Martinsville, VA. There are many Redmonds in NC, especially in the mountains, but the surname was not a common one in the piedmont section of the Tarheel State". However as we look through the descendancy of Oliver, we will see the name Redmond show up many times. Further research on the Redd and Redmond families will likely be required to solve this little mystery.
