In my opinion,
Constantin is the name for a Male which matches the name
Helen perfectly.
St
Constantin was the
Roman emperor which issued the edict of
Milan to permit the
Christian religion and to disable violations over Christians.
His mother was St.
Helen. She was a
Christian. She influenced her son. Today's Christians are obliged to St.
Helen for the Sancta Crux, the sign on the top of each
Christian temple.
Constantin and
Helen would have the same name day -
May 21.
