avoidance of the proper name

[Caorthine]

What/who[m?] does the New England avoidance of the proper
name in this excerpt from Edith Wharton's novel Summer refer to?

"No, I suppose not." He laid down the book he had been wiping, and stood
considering her in silence. She wondered if Miss Hatchard had sent
him round to pry into the way the library was looked after, and the
suspicion increased her resentment. "I saw you going into her house just
now, didn't I?" she asked, with the New England avoidance of the proper
name. She was determined to find out why he was poking about among her
books.


I just can't see what she's is avoiding. Comments, please!

She's avoiding mentioning Miss Hatchard by name - as made clear in the following paragraph. It is implied that New Englanders are shy of being too outright in what they ask.

Thank you, Anglika.
