The origins of the Welsh name Gwillim go back to those ancient Celts known as the Britons that once occupied the hills and Moors of Wales. This old Welsh surname is from the personal name Gwilliam, which is a Welsh form of the name William.

The name was anciently found in Normandy, France where it was more often than not spelt Guillem and by the Conquest was often seen as Guillaume. 1

Early Origins of the Gwillim family

The surname Gwillim was first found in Cardiganshire where the fist on record was David ap Gwilym, the celebrated Welsh bard. There are two thoughts as to his origin. The first claims that he was born at Bro Gynin in the parish of Llanbadarn Vawr, Cardiganshire, about 1340 and died there about 1400. He was buried in the abbey of Ystrad Flur in the same county. The second claims he was born near Llandaff, Glamorganshire in 1300, and to have died at the abbey of Talley, Carmarthenshire, in 1368. 2

What is not in dispute is that his parents were Gwilym Gam, a descendant of Llywarch ab Brân, one of the fifteen tribes of North Wales, and Ardudful, sister of Llywelyn ap Gwilym Vychan of Emlyn. He took to studies in Italy and by the age of fifteen, he had returned to Wales where his satirical whit became famous.

He fell in love with Laura for whom he wrote 147 poems. In his lifetime, he is known to have written 262 poems which were collected and published in 1789. "Other poems by him have since been discovered among the manuscript collections of Welsh poetry in the Mostyn library. The British Museum possesses many manuscript copies of his poems. " 2

At about the same time or perhaps earlier, John ap-Gwilym was Chancellor of St. David's in 1351. The name was also a forenames in East Cheshire. Gwilliam ap Griffith was listed as holding lands there in 1450. 3

Gwillim Spelling Variations

Compared to other ancient cultures found in the British Isles, the number of Welsh surnames are relatively few, but there are an inordinately large number of spelling variations. These spelling variations began almost as soon as surname usage became common. People could not specify how to spell their own names leaving the specific recording up to the individual scribe or priest. Those recorders would then spell the names as they heard them, causing many different variations. Later, many Welsh names were recorded in English. This transliteration process was extremely imprecise since the Brythonic Celtic language of the Welsh used many sounds the English language was not accustomed to. Finally, some variations occurred by the individual's design: a branch loyalty within a family, a religious adherence, or even patriotic affiliations were indicated by spelling variations of one's name. The Gwillim name over the years has been spelled Gwilliam, Gwuilliam, Guilliam, Gwilliams and others.
