There is a listing for an Earl H Rader in the Berks County Register of Wills marriage index, but his marriage application is dated 8/18/1922, so it seems unlikely he is the son of your Henry. There is a "Harry" A. Rader, application date 6/26/1920, in the index. Harry is often a nickname for Henry. See http://www.berksregofwills.com/berks_marriage_1_search.asp. No Clara Bright is listed.
