MAGNUS
MAXIMUS'
ANCESTRY
Mysterious Background

Magnus Clemens Maximus was born in Galicia on the Iberian Peninsula in the mid 4th century. Though from a Roman household, his origins are confused. He was certainly a relative of the Comes Theodsius, whose son was to become Emperor Theodosius the Great, but Welsh writers tell us more.

The popular story says he was the son of a Romano-Briton, named Lolelinus (or Llywelyn), who had travelled to Rome and become a senator in the Imperial Senate. Coel Godhebog (the Magnificent) was thus made Maximus' uncle, and the Emperor Constantius Chlorus, the husband of his cousin, Helena. However, the chronology is all wrong.

Geoffrey of Monmouth wrote that Maximus was of Imperial descent, and early Welsh genealogical tracts seem to back up this idea, showing Constantius' son, Constantine the Great, as Maximus' grandfather. There is, however, little room for such a relationship in the Imperial family tree, as currently understood at this period. It might just be possible that there was an extra, currently unknown, son of Constantine who lived to become Maximus' father, though it seems unlikely. His name may have been something like Maximianus Constans, a combination of those sited in Welsh sources. The former was certainly Geoffrey's name for Maximus himself. Blackett & Wilson, however, claim him as a lesser known son named Flavius Julius Crispus.

The Harleian MS.3859 gives Maximus' ancestry under the pedigree of the Kings of Dyfed, thus:

The Jesus College MS.20 gives Maximus' ancestry under the pedigree of the Kings of Glywysing, thus:

Magnus Maximus married at least twice, though which came first is unknown. Likewise, the birth order of his children is unclear. Britannia suggests the following:
