For your research interest, Rebecca Boyle's old home survived the construction of the Mullaghmore Airfield in 1941 and still stands in a small copse of trees in Landagivey.
In St Mary's RC graveyard, Cullycapple Road lies the following:
WJ Boyle of Garvagh & Landagivey d. 8 Feb 1943, Row 1 Plot E
Hugh & Rebecca Boyle of Landagivey, Row 1 Plot 7
William Boyle of Landagivey, Row 5 Plot 8
Jim Boyle of Agivey, Blacksmith, Row 6 Plot 3
Dan McKaigney & Susan Boyle of Drumale, Row 10 Plot 1
Unnamed Boyle of Mullaghmore, Row 11 Plot 2
In the ancient south east section lies Tom Boyle of Glasgort, a weaver. Row 1 Plot 5
That's all I have for now.
