Seeking info on parents (or family) of George E. Sherlock, my g-g-grandfather, born Dublin, circa 1800-1805, married Catherine Cullen (IRE) at St. Nicholas Church, Liverpool, on 5 July 1826. Emigrated to Brooklyn, NY, sometime after. John Vincent Sherlock, my g-grandfather, was born in Brooklyn in 1838. George & family returned to England/Ireland sometime after 1840, later, with his family, sailed on British Ship Bland from Liverpool, arriving New Orleans 12 March, 1850. Any info on family links would be greatly appreciated.
