military awards

I’m seeking anyone with knowledge of retroactive, posthumous military awards given to NON-PRIMARY family members of deceased servicemen, i.e nephews, nieces, cousina, aunts, uncles, grandchildren, and all varieties of “great”xxxx.  Please provide sources is available.  Examples such as:

DFC to a great grandson:  https://www.defense.gov/News/News-Stories/Article/Article/1218587/fallen-world-war-i-aviator-gets-posthumous-distinguished-flying-cross/

Silver Star to a great nephew:  https://www.washingtonpost.com/local/seventy-six-years-after-he-died-at-pearl-harbor-a-chaplain-will-get-a-combat-medal/2017/12/06/2bb8b15a-daa6-11e7-a841-2066faf731ef_story.html

Thanks!
