Perhaps some death record will give more information - or an obituary.
If, as the SSDI shows, Lillie was born in 1901 - she must have married young.
I believe the 1920 Census probably has an error in the date of birth. And she had her married name in 1920 and was living in Cook (Chicago),IL
You may already have all this information.The other thing to look for is at the 1900 Census for Allens in the 1900 US Census with a daughter named Lillian or Lillie, in the Chicago, IL area or the St. Louis, MO area.
The application for Social Security by Lillie Allen might have more information.You can order one on-line. There is a fee.
