In addition to keeping scrapbooks, which his great granddaughter Mary Mooney Lesch has and is digitizing, O'Neill kept a lot souvenirs of events he had attended or at which he had served as judge, Below, from one of his multiple times as judge at a highland piper's contest
And from one of his two trips to the annual convention of Chief of Police
He belonged to Irish American societies and clubs: Below a medal from the "United Irish Societies" Meeting of 1902
