I am trying to determine the date of death of my Step-Grandmother Margaret Henry.She was born on August 23, 1866 in Killaig, Macosquin, Coleraine, Co. Derry, the daughter of John and Mary Anne Henry. On February 28, 1912 she married my Grandfather, widower Matthew Henry (1858-1938) in Killaig United Free Presbyterian Church of Scotland. In 1930 or 1932 they sold their farm at Blackheath, Macosquin and bought Ultimo House and Farm at Ballymoyle, Coagh, Cookstown, Co. Tyrone. In 1938 my Grandfather died and I believe my Step-Grandmother Margaret died between 1942 and 1950. I seem to recall going to her funeral when she was buried in Killaig Church Burying ground.
Can anyone tell me when she died or how I can go about finding out.
