Their father was John Pope, probably born in the Carolinas c. 1802. John Sr. was one of four siblings who were among the very first white settlers to cross into the Florida panhandle in about 1821, before Fla. was even formally organized as a territory. (The first territorial governor, William Pope Duval, was probably a kinsman). These four siblings were children of Samuel II Pope, d. Barnwell Dist. SC 1816, who had fought in the Revolution with a unit from N.C. The others, in addition to John, were sisters Elizabeth and Catherine and elder brother William Stuart Pope (1789-1837) my second-great grandfather. Elizabeth Pope m. John Tanner; their son John b. 1826 was a Captain in the 11th Fla. Vol. Inf. and their grandson, also John b. abt. 1841, was captured and died in a Northern prison.
The father of the three soldiers mentioned, John Pope, lived in what is now Jackson Co., FL from about 1820-27. He served in the territorial legislature, as did William. William had a son, Henry Pope 1826-1861 who was a captain in a FL unit but died early in the war. John Pope left Jackson Co. FL abt. 1827 and married Rebecca, I think her family name was Looters. They lived for some years in Clarksville, TN on the Kentucky border, and by 1850 were in Hood County, Texas where I believe they owned a hotel.
The three Pope brothers in the 17th Texas all survived the war. I believe Green and John have living descendants.
