[...] who take their Name from Hameyde, one of the two and twenty Baronies of that Province; thus D'Or a trois Hameydes de Geules, that is, Or, three Humets Gules, or Bars couped;
Where it comes from
Uncertain. The OED speculates that it might derive from Old French heaumet (whence helmet), a diminutive of heaume (“helm”) supposedly applied to the bar of it; however, compare the early (1600s) use of humet for a slab of stone or tombstone.
