Too Many Questions
Not only did Mildin become a part of the tribe, he even married five of the local women and had four children while he lived there. But Mildin eventually left the village after his tribe rivaled with another tribe. Over a number of years, he made his way 250 miles up the coast, eventually reaching a trading post. And within months, Mildin was on his way back in Britain.
So the question (or at least one of the many) is, did Burroughs know of this real-life Tarzan? And if so, why didn’t he acknowledge his inspiration? Llewellan noted that Mildin’s death and the details of his adventures were kept secret due to complications in his will. Then again, it could just be that Llewellan himself made the whole thing up.
