I don't know anything of the Hogans, but I know that John Presley McKenney (b. 1855) was the son of Samuel and Priscilla R. (Sutton) McKenney. Priscilla married Samuel January 5, 1847 in Westmoreland Co, VA. She died May 9, 1883 and her son John Presley supplied the info on the death record. Priscilla R. (Sutton) McKenney was the daughter of William and Priscilla (Brown) Sutton. William Sutton died about 1832. Priscilla (Brown) Sutton died in March of 1850 leaving a will mentioning, among other children, her daughter "Cilla" (Priscilla R. McKenney). I have more info on this Sutton family if anyone is interested.
