Her name is Mrs.O'Hara, and she has a daughter.
When Lady Scroope had read so far, she almost let the paper drop from her hand.

Of course she knew what it all meant.

An Irish Miss O'Hara! And Fred Neville was spending his time in pursuit of this girl! Lady Scroope had known what it would be when the young man was allowed to return to his regiment in spite of the manifold duties which should have bound him to Scroope Manor.
I have seen this young lady, continued Lady Mary, and she is certainly very pretty.

But nobody knows anything about them; and I cannot even learn whether they belong to the real O'Haras.

I should think not, as they are Roman Catholics.
