I didn't know her but I got curious (for you unusually left out her date of birth). Most accounts of her life give the age at her death as 29 and give no date of birth. I've found only one short biography that reports her date of birth as September, 17th, 1900, which would make her 28 when she was killed.
28, widowed(?), with five children and some more dead and a songwriter and a possible threat to company owners makes her an astonishing and admirable woman.
