Cinthia Hoy died in Macon, Bibb County, Georgia about 1874. Her estate was administered by William J. Dent. He was William James Dent, eldest son of John Washington Dent and his first wife, Elizabeth Hoy. Elizabeth did not have a sister, so I am baffled as to the identity of Cinthia.
In Bibb Co., GA in 1870, I found a Mary Hoy, age 40, residing in a hotel in Macon, GA. I did not find a Cinthia, but perhaps her name was Mary Cinthia Hoy?
