MacIlmoil History, Family Crest & Coats of Arms
The surname MacIlmoil comes from the original Irish Mac Giolla Mhaoil, (devotee of St. Michael) from "maol" meaning tonsured or bald. 
Early Origins of the MacIlmoil family
The surname MacIlmoil was first found in County Monaghan. The McElmoyle variants are distinct and are found in Antrim and Derry.  Over in Scotland, records are quite late as in "Mc illemayll 1636. Mary Ncllvoil, 1704, appears in 1706 as Mor Nclllimoile."  However, the same source notes an earlier spelling of "M'Ilmoil (M'Gille Mhaoil). An Islay surname now sometimes rendered [as] Bell. Donald M'Gillemoyll was a sufferer from the hership of Petty in 1502, and John Makmul was bowman in Lochalsh, 1548."  Furthermore,we would be sadly remiss if we did not mention the connection to the MacMillan family. The latter name was derived from the Gaelic name MacMhaolain or MacGhilleMhaoil, meaning "son of the bald or tonsured one." 
Both distinguished authors cited here, one noting Irish heritage, the other Scottish do however, agree in the Gaelic meaning of the surname.

The MacIlmoil Motto +
The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Dieu Garda Le Moyle
Motto Translation: God protects the mule .
