Can't find your family memorial, it may well be they lie in an unmarked grave. I have been able to locate my early twentieth century ancestor's lair by using the burial search. If a lair can be found North Ayrshire Council have a site where you can select Dreghorn Cemetery and get a map to help you locate the lair.
