James Barry (1789 - 1865) and Alan L. Hart (1890 - 1962) were both doctors who were born female and chose to live as men for most of their lives. I feel no qualms about claiming they were both trans men, though they didn’t have those exact words. Hart was born a hundred years after Barry, and I was born a hundred years after Hart. It’s interesting to compare our experiences (would be more interesting if I was also a doctor, but alas).
