You can easily find Herbert Clague Killey in FamilySearch.org, baptized 18 Dec 1892 at Chapel of St Mary Castletown son of Edward Killey & Catharine Killey. From there, you can find at least two others with the same parents, likely siblings. I didn't see a marriage for the parents though. The closest I found was in West Derby Lancashire April-June quarter 1878 of an Edward Killey to Catherine Cubbon

I didn't find anything for Ruth Lucy Corkil born 1898 Maughold in FamilySearch or in the 1901 or 1911 census's. I tried all sorts of combinations on her name, dates, place of birth, etc but no luck.
