This is the situation. Grandfather born William McAllister, name changed to James Mcdonald. His mother died when he was an infant, was taken in by relatives (Mcdonald). Found a manifest with Mary Mcdonald and a James Mcdonald coming from Ireland. According to manifest James was 6 mos., which makes since, could have changed name to avoid red tape with immigration. It was not an adoption thru the courts. I have prayer card on a Mrs. Majorie McAllister. My sister said our grandmother had a piece of paper with Majorie Mcallister with a phone # pinned to a curtain (dont remember number). We are thinking it is his sister in law. We know theres ties in new york. James new parents lived in newfoundland in 1918, according to James marriage church record. Any suggestions how we can tie all this together?
