Well, I hope I was Queen Boudicca, to keep to the Celtic theme of this website. Reincarnation is not my thing, but if it is true I was probably someone normal and boring.
Boudicca married into the Iceni to strengthen the alliance with her own Tribe, the neighbouring Trinovante.
The Trinovante were already well established here by 500bc when the last Celtic diaspora began. And the name Tri-novante in Roman Latin means "New Trojans". Which, along with other pre-Celtic artifacts, and myths, and the presence of Arcadian Greek Temples being the first buildings in what is now, London suggests that the origins of Boudicca's Tribe, were refugees from Troy. The earliest ever recorded War.
Boudicca's hair was famously red, and her eyes were green. And there are only two geographical markers for this rarest of eye colours. I've known for a long time that one of them was Scotland. And the other? Turkey. So Boudicca may have been descended from Priam and Hector's line.
Another interesting fact is that instead of the practice of (by 50ad) inheritance being passed through the male line, like all the other English (but not Irish) Celts, and the Gauls, Boudicca's recently deceased Husband was only King Consort. The Trinovante/Iceni/& Durotriges alliance counted lineage from the Distaff. So when her Husband died, the Romans misunderstood, and thinking that the Tribe had no King, turfed Boudicca out, as old baggage, and put the raep to her three Princess daughters.
They wanted to install a Roman Legate to rule, because The Alliance had not openly resisted Rome yet, and the other Tribes were all riddled with Druids, and kicking off left right and centre. In fact, all of the Legions except the one at Colchester were up at Holy Island, Anglesey, throwing the last of the Druids over the cliffs to drown.
So it took them by surprise when Boudicca's outrage brought the whole Alliance down on them. Within 2 days, they were all dead, and Colchester razed to the ground. Then London too. When news reached Anglesey, the already worn out Legions force marched right down to London, and almost, almost lost the whole of Albion. To a Ginger chick.
