In the 1920 Census my Great Aunt Hilda Gladys Hamilton is living with her husband Harvey in McCook City, Willow Grove Precinct. By the 1930 Census he has moved to Herndon, Rawlins, Kansas but has remarried (1927) and is living with Helene and her daughter Evelyn. I have no idea what has happened to Hilda, presumably between 1920 and 1927 she has died. Can anyone suggest how I can find this out? I have tried various sites online and googled but to no avail!
