Jones is a surname of Welsh origin, meaning "son of Ioan," or other similar names that ultimately evolved from the Hebrew name יְהוֹחָנָן (Yəhôḥānān), Johan for short. When Welsh culture adopted the name, it evolved to variations of traditionally Welsh names: Ieuan, Iowan, Ioan, Iwan, or even Siôn (note how the letter 'J' was originally being pronounced as 'i', akin to how J is pronounced in the latin alphabet).
The surname Jones first appears on record as a surname in England in 1273 with the name "Matilda Jones". Others put the first known record of the surname Jones as 1279, in Huntingdonshire, England. Around the time of the Laws in Wales Acts in the early to mid 16th century, the traditional Welsh system of patronymics was increasingly replaced by surnames, since English was the official state language and all official documents needed to be in English; this led to the Anglicisation of Welsh names, meaning that English Christian names (such as John) became increasingly common to distinctively Welsh Christian names such as Meredudd (Meredith) and Llewelyn. Thus "Mab Ioan" or "ap Sion" (and many other variations) meaning "son of John" became the surname Jones in a large number of cases, making it a very frequently used surname.
20th and 21st centuries
Jones remains the most widespread surname in Wales, borne by 5.75% of the population. The frequency in England is lower, at 0.75%, but still the second most popular surname, after Smith.

Jones was the fourth most common surname in the 1990 U.S. Census, behind only Smith, Johnson and Williams.
