The name William comes from the Germanic name Willahelm, which is composed of two elements: wil meaning will or desire and helm meaning helmet or protection.
After the Norman conquest in 1066 the name William became extremely popular as many English boys were named after William the Conquer, the first Norman king of England.
In fact William soon became the most popular boy's name in England and has remained common right up until the present day - it was the ninth most popular name given to baby boys born in 2012.

Surnames to avoid pairing William with:
Any that you wouldn't want to put the word 'will' before. For instance, the surname Knot. Or if your surname is Way, it may elicit jokes about 'where there's a will, there's a way.' Also, watch out if your surname is Board, as the shortening 'Bill' could prove a tiresome combination.
Surnames beginning with an 'M' might cause problems too, as when said aloud this combination of sounds may result in elision – when two words slurred together end up sounding like one.
