On a trip to Ireland I found the following gravestone in Dundalk, Co Louth, at the St Nicholas Church of Ireland graveyard: “John Blair - late officer of the Irish revenue a native of N.T. Limavady and for 20 years an inhabitant of Dundalk where he died Aug 3rd 1852 aged 71 years Sarah, widow of the above John Blair who died in Dundalk 17th Feb 1866 aged 78 years” I suspect, but don't know for sure, that John Blair was a relative of my ancestor, William Henry Percival, who lived in Dundalk in the early 1800's. If anyone has a Blair family in the Newtown Limavady area of Co Londonderry, please let me know. Thanks, Colleen
