To George - The Doctor, and The Doctor. One born in Australia to an Australian-born father and an English mother, moved to England, "regenerated" in England. The other born in England to that same Australian father, English mother. One married young-ish, the other only a couple of years before he "regenerated". Both had children by women to whom they were not, at the time, married. One qualified LRCPE MRCS, the other qualified MRCS LRCP. The one who married young-ish had five sons by one wife, two sons and a daughter by a second wife (well, technically he had a son and daughter by the wife, the other son happened along before the wedding, while the first wife was still living). He decided to "regenerate" at sea, and so he was lost to the eyes of this world.
I cannot remember a time, since watching the First Doctor on our black and white telly, that I have not referred to the one as "The Doctor", and to his father as "The Judge" (which actually became even more of a thing for me during the era of "Rowan and Martin's Laugh-In"). It was later, on discovering that The Doctor had a brother who was also The Doctor, that my little imp simply could not be restrained. (Kind of like telling nose-in-the-air church folk (and that's too long a tale to tell in this medium) that I was a direct descendent of Mary and Joseph and could prove it. I don't take being treated like feces on a shoe with good grace.)
