Looking at your post on the Burnside message Board looks like the Lell Leonard Burnside is the man you are looking for. A family tree lists same parents you post for sister Opal. My condolences for your recent loss. Lell's next of kin can order a copy of his Navy service record form NARA be sure to note the service number.
Looks like the family got his name, as well as the details of his death a little mixed up through the years.
In 1930 census for Albq..Bernalillo, Co NM. wife Vera Burnside is head of household married about 3 yrs with 2 daughters. Haven't found Lell yet. He is in Duke, Jackson Co OK with parents in 1920 census.
