Mine are from Essex, particularly Tillingham and Burnham on Crouch. So far they've used Moul / Moule / Moull / Mowl / Mowls / Mole... and probably more!
Ah! Mine are from Taunton, Somerset so probably not a close connection (if any) they have also had many variants but my lot are mainly spelled Maul - probably the dialects!
