Hello Maurice.
Mary is listed as a widow in the 1920 and 1930 Censuses (her son T. W. is living with her), but on 1940 (after T. W. got married), Mary is listed "Divorced" (line 18, just above her sister Callie):
Taking into account all of the above mentioned, there is a great chance that Alfonzo A Allen in the other answers is T. W.'s father.
You are welcome, Maurice.
