Sara / Sarah Doyle born approx 1820, had at least 5 children to George Donnelly and possibly 7. The children were Baptised in North Dublin. The grave in Glasnevin where George Donnelly is interred, has others mentioned in the site, including those with Doyle and Donnelly as their names - their connection is only guesswork so far as their details are quite minimal.
Sarah's middle daughter is Mary Elizabeth Donnelly and is my Great Grandmother: Mary's details are under her name on this site.
She married in Dublin to a soldier, Christopher Clements Baddock, early 1880's and left for the UK [England] mid 1880's.
