Willey, of Germanic origin, is a unique and historic name derived from 'Willhelm', meaning 'resolute protection'. It was popular during the Middle Ages, particularly among the Norman nobility who brought it to England after the 1066 conquest. Willey was also used as a place name in Shropshire, England, further cementing its association with British history.
"Willey appears to have been a moderately popular name during the early-to-mid 20th century, with peaks in popularity around the 1920s and late 1930s. However, it seems to have fallen out of favor by the mid-20th century."
