T. Tembarom by Frances Hodgson Burnett (1849 - 1924)

The story of a Boy living in New York as a street waif, who sells newspapers eventually finds himself to be the heir of an ancient manor. The kids at school never understood what the "T" was for in his name, and he didn't tell them. Does that have something to do in the story? And what about this ancient manor? Summary by Elijah Fisher
