Couple of ways to interpret/record this.
1. If it is a dual stone and both are listed as husband and wife on the stone, I sometimes put in the NOTE/INFORMATION section as "Daniel, husband of Dollie (Moore) Gray."
2. If I have to do any research on them, and I can document the marriage date, then I will add the marriage date in the fields for it, and indicate in INFORMATION where I got the date (SSI, or State Death Index etc.
Hope this helps.
