William Chalker served in the War of 1812, was in the Battle of Petepany Point April 8, 1814 - Captain Clark’s Company, Col. Platt’s regiment, Connecticut Militia. He was probably captured off the coast of South Carolina during the War of 1812 which accounts for his being in that state where he married Nancy (Nannie) Stanaland near Georgetown in 1816. The family moved to Florida in 1851 and settled in Marion County near Ocala. William died April 10, 1867 and was buried in the private Chalker Cemetery there.
