That death looks right for Richard Ager.
Esther was born 1816 Gt Creaton she married Charles Hare at St Sep 23rd Aug 1838.
Esthers father was called Edward that was the Edward Masters grave that you found for me. So don't think that would be the marriage that you found .
I can't find Esthers husband Charles at all on the census's but I can see Esther on 51 and 61 living with Richard, can't find a marriage but she died with the name Ager, I think that is her 28th June 1863 with the name of Ager so a bit confusing did they do that in them days die with the name of the surname of the person they were living with.
