Thank you for your prompt reply. We are searching for a Thomas Horan who would have been born in the 1860's (possibly 1867) which matches the time frame for the Martin and Margaret Horan Family. Further, Thomas Horan had a son named William Martin Horan (born 7-27-1893). Thomas died unexpectedly in the 1890's when Willam was small and after 1905 William Martin Horan re-named himself (after his mother's remarriage) to honor his father Thomas, thereafter known as William Thomas Horan. Patrick's son Msgr. Edward G. Horan was allowed to peform the marriage ceremony of his "cousin" Helen, the daughter of William T. Horan at the Cathedral of the Holy Cross in Boston in the 1940's because he was working there at the time and also because she was related. I am going to the Irish website you suggested to try and find this Thomas Horan. There is a passenger Thomas Horan (born 1867) who was from Roscommon Ireland and arrived in the Port of New York in the late 1880's which jibes with oral family history as Thomas being a "recent arrival" from Ireland. His wife Sadie Burke Horan was born in Boston in 1874 and was just 19 when William Martin Horan was born.
