The SSDI lists a Margaret Kildare, born 1896, died 1991, last known residence Rye, Westchester, NY. The 1920 US census lists a Margaret Patterson in Mamaroneck who married Frank Kildare between 1920 and the 1930 census, which lists them as married and living in Mamaroneck. Margaret's father John Patterson was my grandmother's half-brother. I would appreciate hearing from anyone who has information on this family.
