Capt. J. B. Johnson died at his home in Fingerville, September 10th, 1880 - aged 41 years, 4 months and 10 days.
He was a native of Virginia and migrated to Tennessee, and went from there to the late war. At the close of the war, not being permitted to return home, he taught school in the neighborhood of Fingerville and New Prospect, where he met and married Miss Candace Finger.
Soon after the marriage he moved to Texas and was a native of that sate about six years. His wife's father dying in August, 1873, they returned to South Carolina, and in connection with his brothers-in-law, he was building up the interests of Fingerville factory and surrounding country.
Two years ago he was attacked with hemorrhage of the stomach, which so broke down his seemingly strong construction that he never recovered.
Brother Johnson died in the faith. He was converted when a boy, but did not join a church until after his marriage and settlement in Texas. There he attached himself to the Cumberland Presbyterian, but on his return to South Carolina in 1874, he joined the Methodist Church at Fingerville, and was useful in promoting its different interests.
