Deletion of Endrid Bookling

Comment: Spellings in historical documents are frequently erratic.  However two of the references are to Einridi Bookling and only one to the other spelling, so that I would suggest rename to that.  The Source cited should be cited more specifically as "Icelandic Sagas etc concerning The British Isles: IV Saga of Hacon (trans. Sir G. W. Dasent), Rolls Series 1894".  As we known neither dates of birth nor death, it may be best to give his dates as floruit 1217-22.  Any specific dates would offend against
