Not related, I live in Texas but not Harris county and found no matches in Texas death records for Lula Glass in Harris county or Aletha M Lanagan [sic] and nothing found on a "Jack"/John E Lanagan.

I see from 1930 census Doris is listed with middle initial "L" . There are 26 Doris' born 19 Jan 1923 listed SS Death Index. She had no children in Texas.

One Doris Lee Wohlgamuth born 19 Jan 1923 died 12 Mar 2004, last residence Saint Petersburg, Pinellas, FL, ss issued WVa. She was also listed in public records in Evansville, Indiana 1996 - 2002.

I found Tuskco Thomas Stillwell, born in TN, and maybe Aletha and Lula in Big Creek, McDowell Co in 1920 census as CALL. They had not yet married when 1920 census was taken.
