PANB:MC1156 Graves Papers: Robert J. Ritchie, 1 page
see also PANB: MC80/338 I. Allen Jack’s Biographical Review, pgs 343-344 which says Marmaduke died in 1887: Francis Hunter came from Kings County, Ireland to NB in 1819: settled in Saint John County. (Kings County, Ireland was renamed to County Offaly in 1921. This can be confusing to researchers since there is a Kings County in New Brunswick)
