Biography
Conanus (known as Cynan in his native language) was born in Wales, in 305 AD. In 325 AD, he married Ursula, though she was later killed when the Huns sacked Cologne. In 229 AD he remarried, marrying Dareca of Ireland.

When his old uncle Octavius' sons all predeceased him, he expected to inherit the title of Praeses from him. But his cousin Helena married a Roman named Magnus Maximus, removing any chance of inheritance. Angry, he rebelled against Magnus, but was defeated and came to accept him as a good friend.

When his cousin-in-law set off to conquer Europe, Conanus accompanied him and even slew the leader of Brittany, which he was given as a gift.

Though Brittany was well settled, there was a lack of wives, so Conanus called on Dumnonia to send him Cornubian women.

He died of old age in 395 AD. Dumnonia and Brittany were given to his two eldest sons, Catamanus and Urbanus.
