My theory is the Philip James Mylrea migrated to Australia where he was known as James Mylrea - theory will not hold water though if he had a wife Elizabeth. He would have had to leave IOM by 1844. My only justification is his dob and the fact that he was referred to as James in his father's will. Have you seen Elinor's will where she leaves a greater portion of her assets to Ann? I wondered if Ann had stayed on to look after her mother.
