Private Jacob C. Cannon was born ca. 1837 in North Carolina.
In 1860 he was living near Blue Creek, Liberty County, Florida, at his father Ira’s residence along with his mother, four younger brothers and four younger sisters. He married Mary A. Boykin on January 23rd, 1862 at Gadsden County, Florida.
He enlisted in Davidson’s Company on May 8th, 1862 at Rico’s Bluff, Liberty County, Florida. His younger brother, Thomas, enlisted in the same company in March. John was listed at sick at Liberty County prior to June 30th of 1862, but rejoined the company after that date and was with it until October 24th, 1862 when he again took ill and was admitted to the hospital at Knoxville, Tennessee. He returned to duty prior to November 12th, 1862 and was with the company until August 30th, 1863 when he was again admitted to a hospital for illness, this time at London, Tennessee. He appears to have returned to the company prior to November 25th, 1863, because he suffered a pay stoppage for “ordnance stores lost” between November 1st and December 31st, 1863 in the amount of $55.85; this likely due to the Confederate defeat at Missionary Ridge on November 25th. He suffered a gunshot wound to the left groin at Kennesaw Mountain, Georgia on June 15th, 1864. The wound was of such severity that he would not return to service; he surrendered at Quincy, Gadsden County Florida on May 11th, 1865 and was paroled from there eleven days later.
Jacob was awarded a Florida Confederate Pension. He died on March 29th, 1893 and is interred at Providence Baptist Church Cemetery, Quincy, Gadsden County, Florida.
