Mylls Last Name: Meaning and Heraldic Roots
Mylls is best understood together with Mills: both are English and Scottish spellings of a single family name.
Census takers and immigration officers often wrote what they heard. The two spellings differ in a small detail: Mylls has “y” where Mills has “i”.
A coat of arms belongs to a particular family line rather than to everyone named Mylls, so the heraldry linked to Mills is a starting point, not an automatic right. Get the complete Mylls report, with a museum-style coat of arms.
