Stephenie,
Looking for information on William Brock, possible from Ga., birthdate unknown, possibly about 1845-1850.Was a Babtist minister in the Ok Cherokee indian nation in the late 1800's. Married a "Charokee Indian Woman", had at least one daughter named Mollie, born in 1874. Mollie Brock was my wifes grandmother. William may have had a son named Lee as well. This is all the information I have. He may not be connected to your "General Brock". We do not know if he was in the Civil war or not.His daughter Mollie married Elija Cox, migrated to central Tx. and is buired near Temple TX.
