Who is Mrs. Bellamy Storer from The Rise of Theodore Roosevelt and what is their importance?

When Roosevelt begins to feel discontent with his position in the New York Police Department, he seeks an appointment as assistant secretary of the navy. He seeks to influence the right people around future president McKinley, including one of McKinley's most generous contributors, Mrs. Storer. She upholds her end of the deal, traveling to Canton, Ohio to put a word in for Roosevelt shortly after the voting results come in.

Later, during Roosevelt's governorship, Mrs. Storer pleads with Roosevelt to intercede for the promotion of her favorite cardinal. Though Roosevelt does not desire to interfere in such a matter, he writes the president, who refuses to help. Consequently, Roosevelt falls out of favor with Mrs. Storer.
