Searching for information regarding my ggrandparents or their children of County Down, Ireland. GGrandfathers' name is William McQuade and Ggrandmother is Mary Ann Boyce. Their children were John(b.16jan1869), Margaret Jane(b.12may1871), William(b.18jan1874), Isabella(b.23mar1880) and my grandfather David(b.17mar1883). Different birth records show surname as McQuaid for Margaret Jane and for Isabella and also for their parents. Birth records were mostly filed in Waringstown, Lurgan and also for Ballymacanallen and for Gilford. Mary Ann Boyce may be from Donacloney, Waringstown but have been unable to make a solid connection there. David and William(jr.) both emigrated from Ireland via Liverpool to upstate New York between 1902-1909.
