William Niemi

(male) Probably the most successful of all the Old French names of Germanic origin that were introduced to England by the Normans. It is derived from Germanic wil ‘will, desire’ + helm ‘helmet, protection’. The fact that it was borne by the Conqueror himself does not seem to have inhibited its favour with the ‘conquered’ population: in the first century after the Conquest it was the commonest male name of all, and not only among the Normans. In the later Middle Ages it was overtaken by John, but continued to run second to that name until the 20th century, when the picture became more fragmented.

Finnish: from niemi ‘peninsula’, ‘headland’, originally a habitational name from a farm so named for its situation. In the late 19th century it was a popular ornamental adoption, so much so that people then began to change it for a less common name. It occurs chiefly in western Finland. In America, it is also found as an abbreviation of other surnames containing this element, such as Rajaniemi, Sotaniemi, and Syrj(a:)niemi.
