Hi, Kiki.
For 8d.,
Start with another word for "bury", and add a word for "a large landed property" or "what executors of a will administer", with the abbreviation for "river" inserted.
The whole answer can be found on credit card statements!

For "islander", on the outside, another word for "bed", as in "bottom level of something", and inside another word for a "row" (rhymes with "wine"!)
The whole is a native of an island east of Java!
