Son of William. Welsh 'ap William' compressed by the same Tudor-era administrative pressure that produced Jones — the genitive 's' added in the English fashion. William itself had arrived with the Normans and embedded across Wales by the late medieval period, particularly through the Marcher lordships.
The history of Williams
Williams is the second most common Welsh surname, generated by the same patronymic-to-hereditary compression that produced Jones — but with a centre of gravity further north. Caernarfonshire and Anglesey produced more Williamses per head of population than anywhere else; the surname tracked the migration south into the slate quarries of Bethesda and the docks of Liverpool, then onward to North America and Patagonia.
The Williamses of Cochwillan, near Bangor, and of Penrhyn, are the principal landed line — Tudor-period gentry rich on slate, who would build Penrhyn Castle in the 19th century from quarry money and Caribbean sugar. The line is documented; most Williamses descend not from them but from the same generic Tudor-era patronymic compression that touched every parish in the country.
Outside Wales the name became one of the foundational surnames of the American South — partly through Welsh Quaker emigration to Pennsylvania in the 1680s, partly through the later 19th-century coal- and slate-driven diaspora.
