Bit of a mystery here

CWGC lists Patrick as "Son of Mrs. Mary Diamond, of Gortmacrane, Kilrea, Co. Londonderry"
http://www.cwgc.org/find-war-dead/casualty/756846/DIAMOND,%20PATRICKHowever, research done for the Kilrea War Memorial shows his parents as John & Alice of Claragh (opposite side of Kilrea from Gortmacrane although not too far away).
Here's what I have on that Claragh family-
