The only additional info I have obtained is that David Roche was a blacksmith.Another David Roche, possibly a son, also a blacksmith (NY City Directory. Lived NYCity.Children of David and Catherine Austin mostly born there, including my ggrandmother Margaret. Hoping to find descendants of Margaret's siblings. Have no clue where they came from in Ireland.If I find the death certs for David and Catherine, it might say. PS- Margret's husband Daniel Shea was also a blacksmith in Stamford, CT, then NYCity most of 1890's, then back to Stamford.
