John Isbell at Timpson
While this church is not in Rusk County, the information applies to former Rusk Countian John Birdwell Isbell (that he was in the BMA side of the Timpson Church split). It also suggests the Baptist Church at Timpson split in 1901 rather than 1902 (but there is probably more to learn about this).
