The only children attributed to this Nicholas Long in his pension application are Gabriel Long, William Long, and Mary H. Colwell. Gabriel and William had previously died in Texas, and Mary H. Colwell is mentioned as the sole surviving child as of 03 January, 1851.S1

Other sources cite bible records of Nicholas Long and appear to indicate additional children, including the above named Richard. Can anyone provide sourcing for this with location of these records?
