For all seeking connection with the surname Ellestad. 1.This is the name of three farms in Vestre Slidre, Oppland, Norway 2.Many who owned these farms took the name Ellestad when it "was necessary" to have a surname. 3.Many who worked on these farms (i.e. laborers or sharecroppers) also took the name as in Norwegian "fra Ellestad" (from Ellestad). 4.There are hundreds of people with the surname of Ellestad who are mostly likely NOT related.
I know all this because I read both Norwegian and Swedish and have searched through many church books via the Internet.I have also been there several times and searched manually BEFORE these books were digitalized.Your only hope of finding relatives is to search "backward" from your oldest known relative.
