Why was Mattie's mother so anxious to have tea with the Ogilvies?

In chapter
7, Mattie's mother is quite anxious about having tea at the Ogilvie mansion for a couple of
reasons.

First of all, the Ogilvies are extremely wealthy and belong to the
upper crust of Philadelphia society. This is made quite apparent upon their arrival at the
estate. The Ogilvie daughters are dressed in expensive matching outfits and are learning French
from their own private tutor. They talk about their connection to the Washington family and that
Colette Ogilvie is engaged to the son of Lord Gathering. Mattie and her mother are rather out of
place in such a setting.

The true reason for Mattie's mother's anxiety and
eagerness is shown when she asks about Mrs. Ogilvie's sons. It becomes clear from her repeated
questions that she would like Mattie to marry one of the Ogilvie boys. Of course, this would be
marrying down for an Ogilvie, and the conversation goes nowhere. In fact, it ends with a verbal
fight between Mattie and one of the Ogilvie girls.
