He came to the state in 1848, settling first in Harrison County.He came to Palo Pinto County in 1856 and established a stock ranch seven miles north of Mineral Wells on what was known as "Betty's Prairie".On his way here he passed through Weatherford on the day when Parker County was being organized into a county. When he came to Palo Pinto County the Indians were thick here and farther west and two years after coming here he took an active part in what was known as the Baylor campaign against the Indians at Paint Creek and the fight which followed resulted in a complete rout of the Indians, who retired, leaving their dead. Betty and his wife were among the first to reaach the Sherman ranch after the brutal murder of Mrs. Sherman by the Comanches in 1860, which fixed in the minds of the settlers the determination to wipe out the Indians in this section. He was the father of thirteen children, of whom eight are living.They are R. C. Betty, Jr.; Temple, Oklahoma; N.S. Betty; San Dimas, California;Mrs. J. G. Moss; and Mrs. D.
