Henry descends from a Germanic compound joining "home" or "estate" with "ruler," and its traditional sense points toward domestic authority rather than conquest abroad. The name has long carried an association with stewardship -- leadership measured by what's cared for and maintained, not simply commanded.
When the Sun in the daytime, and the Moon in the night, in the beginning of any sickness, is impedited, the person is to be feared. - William Lilly (1602.-1681.)
