I have finally found out the date of marriage of my great grandparents James Byers of Greaghnagee and Mary Anne Byers of Aghalohan.They were married on 6 March 1884 in Bellasis presbyterian Church, Lurgan, Cavan. Both James and Mary's fathers were called Robert Byers.I believe James father Robert married Anne Jane McQuade in December 1850 in BellasisPresbyterian church. His address is given as Drummolard and Anne's is given as Lisnabantry. They appear as living at Lattagloghan townland in the 1901 census. If anymore has any more information about these families I look forward to hearing from them.
