I dont think little boys ever really knew pilots' names to the extent you imagine, P-N. When our primary class teacher asked us to name our heroes (c1957), just about everybody picked a footballer. When I named Peter Twiss nobody, including the teacher, had heard of him, in spite of his holding the world speed record at the time.
Struggling with one or two of the names on your list, except Hannah of course, and Ward, but the latter for all the wrong reasons!
