I'm searching for my great grandfather, Murray Stewart, who I know went to South Africa from Scotland sometime before 1941.  I have found a record on family search of his marriage to Elizabeth Jane Bellord (nee Billing) in Jan of 1941 (he was previously married in Scotland to a Grace Neilson).
I have been searching for other records for either Murray or Elizabeth in South Africa, and came across her death in 1951 in East London, South Africa, also on family search.  She is listed as a widow.

I have had a much harder time with the NAAIRS database, but just came across this hit. Could someone tell me what type of record it is (is it perhaps his death) and how I might get access to it?  Thanks so much in advance!
