I think I need to know who your grandfather was in order to know where your family fits. I have found two AR Dancers who may be part of your family in the Social Security lists.
Mary Dancer, born 16 August 1917 died 25 May 1994 in Dumas, AR.
Herman Dancer, born 26 August 1915 died 6 March 1996 in Monticello, AR
A lady I spoke with years ago told me all the Dancer men were big and strong and many were blacksmiths.
Does the name Bulliner mean anything to you? In the estate settlement for Henry P. Dancer of McNairy Co, TN a daughter or granddaughter had married a Bulliner and moved to AR. Also Samuel Dancer, son of Henry P., had children who had gone to AR.
Descendants of Elijah Dancer's son John Dancer and his wife Sally Kemp were at Conway, AR after the Civil War. I have some of their information but I can't place your family yet.
Do you know of any Aunts or Uncles in the Dancer family? Any piece can help put these families together.
Happy hunting!
Bertie B. Dancer [wife of Mayo D. Dancer, grgrandson of Stephen Pinkney Dancer who was a brother to Henry P. Dancer and both were sons of Samuel of McNairy Co, TN and Tishomingo Co, MS.
