Doctor Thorne

When their father dies, Doctor Thomas Thorne and his younger, ne'er-do-well brother Henry are left to fend for themselves. Doctor Thorne begins to establish a medical practice, while Henry seduces Mary Scatcherd, the sister of stonemason Roger Scatcherd. When Scatcherd finds out that Mary has become pregnant, he seeks out Henry and kills him in a fight.
While her brother is in prison, Mary gives birth to a girl. A former suitor offers to marry her and emigrate to the Australia to start a new life but refuses to take the baby. Doctor Thorne persuades her to accept the generous offer, promising to raise his niece. He names her Mary Thorne but wishing neither to have her illegitimacy made public nor to have her associate with the uncouth Roger Scatcherd, he keeps her birth secret. Mary Scatcherd tells her brother that the baby had died. Wikipedia
