The author of Scandinavian relations with Ireland during the Viking period (Dublin, 1922) is not known for any other works. The catalogue of the British Library has two catalog records for this book and one of them lists the name as Annie. However, a review in The Geographical Journal, Vol. 62, No. 4 (Oct., 1923), as found in JSTOR, talks about Mr. Walsh.
