Rosemary and Bridget Devlin

Rosemary and Bridget Devlin left lower back Stewartstown about 70 yrs ago. They both would be in their eighties or more. They had a fall out with their father and nobody knows where they went. Any info would be welcome. We once heard that one of them married and had one son but thats all we know...the family were known as the "glory" devlin's. Their brother Otto and sister Kathleen, my father and aunt, would like to hear from anyone who has any info about them,any members of their families or anyone who knows of their whereabouts
