The other leading man in the Osage Mission was Kentucky-born John Allan Mathews. He was married to Mary Williams and after her death to her sister Sarah Williams. The Williams sisters were the daughters of William S. Williams and his Osage wife, A-Ci'n-Ga. They first met Mathews while attending school in Kentucky after their mother died. Mathews was a slaveholder and souther-sympathizer. He married Mary in Jackson County, Missouri in 1835 and was appointed blacksmith for the Senaca in 1837 and for the Osage in 1839. In about 1861 he gathered a group of Osage who tried to force Schoenmakers to flee the area because they disagreed with Schoenmakers' abolitionist ideas. Matthews was killed by the 6th Kansas Cavalry under Gen. James G. Blunt in fighting at Chetopa, Kansas on Sep. 18, 1861.
