Aegnor was not a son of Feanor but the son of Finarfin and brother of Galdriel, Finrod felegund and Angrod. He was slain along with Angrod in the Dagor Bragollach. You are thinking of Amrod or Amras....
Seeing Dain, menace and Thonnas joke around has very neerly brought a tear to my eye (before I remember that I am trying to be more manly and go get a beer) Its just like the old days.
