Altered form of an unidentified surname, possibly of the like-sounding Dutch name Janse or its cognate Jansen (final -n is silent in some dialects of Dutch), or of some similar English surname, such as Jauncey or Jancey, variants of Johnsey .
History: Charles Yancey, the progenitor of the Yanceys, is recorded in King William County, VA, in 1704. According to family tradition, the surname was brought to VA from Wales in the middle of the 17th century and is said to be an altered form of Nanney , but there is no evidence of this and, as the DNA tests proved, also no direct paternal connection between the Yancey and the Nanney family.
