I doubt there is a connection here, but my mother's maiden name was ADCOX. Her grandfather, Alford Harrison ADCOCK changed his spelling to ADCOX as well. My ADCOX family has been in Texas since about 1890. They moved here from TN and settled in teh Houston area (Crosby/Baytown). Alford Harrison's father was James Alton ADCOCK. His father was Joel W. ADCOCK.
