Seeking information on the children and grandchildren of James Tilford ALVIS married Mary Elizabeth [NUNNALLY].

From the 1900 to 1930 Tx censuses I found record of 5 chn:
1) Curtis (daughter) married a Mr Minton and died 1972 in Bexar Co Tx
2) Raymond Carlisle died in Wash DC Aug 1973
3) Gladys born abt Aug 1896
4) Irvin Tilford died 1955 Tarrant Co Tx
5) Hallie married Harold C. Fellow 20 Aug 1970 Tarrant Co Tx - this is likely a 2nd marriage as she was age 68 and he was age 78. Hallie died in May 1985 and Harold died Feb 1990. I think they both died in Wash DC.....?

James Tilford ALVIS died between the 1930 Tarrant Co Tx census and his wife's death 28 Feb 1957 but I don't know when.....

========================================================
Not to mislead anyone, I am a NUNNALLY rsearcher thus my interest in this family is because of Mary Elizabeth [NUNNALLY] ALVIS......
I have not been able to find any record of her parents or siblings so I am trying to document her descendants as accurately as possible.
Should I discover new information on Mary Elizabeth [NUNNALLY] or James Tilford ALVIS I will come back and post it to this board.
