I cannot find any of her marriage records. A note on her findagrave page lists the three husbands. I infer the approximate dates based on:

1. The 1950 census has her still with the "Compton" surname.
2. Robert Weaver dies, 1957, so is likely the first husband.
3. James Bevins died 1973, likely the second husband.
4. Charles Brown likely the third.
