I am researching my RISDON surname. My grgrgf, WILLIAM JOSEPH RISDON, born 3/3/1831 in Prince George's County, MD, claimed his residence was Front Royal, VA when obtaining a marriage license in Fauquier Co. VA. Is anyone aware of any RISDON family in Front Royal between 1831 and 1851. After marriage in Fauquier Co. in 1851 he & wife MARY KIRBY resided in Warrenton, VA. Purpose of inquiry is an effort to identify William's parents whom I have been unable to locate in MD, DC or VA counties around DC. Thanks John Risdon in FL
