Loyd Spelling Variations
Compared to other ancient cultures found in the British Isles, the number of Welsh surnames are relatively few, but there are an inordinately large number of spelling variations. These spelling variations began almost as soon as surname usage became common. People could not specify how to spell their own names leaving the specific recording up to the individual scribe or priest. Those recorders would then spell the names as they heard them, causing many different variations. Later, many Welsh names were recorded in English. This transliteration process was extremely imprecise since the Brythonic Celtic language of the Welsh used many sounds the English language was not accustomed to. Finally, some variations occurred by the individual's design: a branch loyalty within a family, a religious adherence, or even patriotic affiliations were indicated by spelling variations of one's name. The Loyd name over the years has been spelled Lloyd, Llwyd, Lloid, Loyd, Loid, Lwyd and others.

Many Welsh joined the great migrations to North America in the late 1800s and early 1900s. Like their Scottish and Irish neighbors, many Welsh families left their homeland hoping to find hope and prosperity in a land that the English did not exercise a tight rule over. Those Welsh immigrants that successfully traveled to North America went on to make significant contributions to the rapid development of both Canada and the United States in terms of the settling of land and the establishment of industry. They also added to the rich cultural heritage of both countries. An examination into the immigration and passenger lists has discovered a number of people bearing the name Loyd:

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: Heb dduw heb ddym, Dhuw a digon
Motto Translation: Without God without anything, God is enough.
