Joseph Franklin (Frank) Cooper
wife:  Ada Brannon

Frank was the tenth and last child born of John Jordan Cooper and Louisa Slay Cooper.
He was born September 5, 1879 at the Cooper Basin homestead in Santa Rosa County, Florida.
Frank  married one of his first cousin's daughters by the name of Ada Brannon. Ada's grandfather, Robert Slay, was one of Louisa Slay Cooper's older brothers. Frank and Ada never had children because of an operation that Ada had when she was a teenager that left her incapable of having children.

The following was from a DeFuniak Springs, FL newspaper clipping in August of 1918 : 

"Frank Cooper was born at Milton, Florida, September 5, 1879; son of John and Eliza (Louisa) Cooper; accepted the restored gospel at an early age, and was a faithful  member for twenty or more years. In and through his influence many souls were won to Christ. Brother Cooper departed this life August 9, 1918. A few minutes before the Sprit took it's flight to the great beyond he said, " Doctor, I wish I was able to explain the difference between the Utah and Reorganized Churches," he knowing that many of our people here in DeFuniak Springs, Florida, did not know the difference. He leaves a wife, two brothers and a sister to mourn."

The two brothers and sister were: James Fountain Cooper, Michael Raleigh Cooper and Susannah Demerah Cooper Adams. His wife's name was Ada Brannon.
