Ok since I do not know the approximate date of birth it is difficult to pinpoint these two. Is Allen a maiden name? Was she ever married. I found a Katie Allen DOD May 1967 in New York on the social security death index the date of birth was Jan 14, 1891. There are also alot of Michael Allens listed in the area and the right time frames. I am looking on Familysearch.org. It is free to use and is a great reference. Maybe it will help you too.
