;’) The British parts of my ancestry appear to be deep Anglo-Saxon (literally, near the Mercia-Wessex interface), and I suspect Celtic, with possible leavening from the wild assortment brought in during Roman times; the Welsh (not sure which kingdom, and for that matter, not sure that’s even true, but then, who would lie about it? That branch vanishes into undocumented a mere four gens back, but I haven’t tried that hard); the Scots (plus I suspect their Pict predecessors, plus another little taste of Roman variety); the Irish; beyond that, could be more.
The only reason I got interested was I wanted to be a part of the oppressed masses slaving away as a serf for an evil frog overlord. I had low self esteem at the time.
After doing some research I found we were the were the evil Frogs and spent our time in England as land owners, merchants, and tradesmen, what a let down.
