Alice's significance didn't lie in herself, but because she had a half-brother, Theodore Roosevelt Jr., who was currently serving as the Assistant Secretary of the Navy!
He was also the eldest son of President Theodore Roosevelt!
Alice's mother, Alice Hathaway, was Theodore Roosevelt's second wife, whom he married after divorcing his first wife, Edith Roosevelt. However, Alice Hathaway died in childbirth when Alice was born.
Consequently, Alice and her mother were born and died on the same day.
After Alice Hathaway's death, Theodore Roosevelt remarried Edith Roosevelt.
(In reality, Alice Hathaway was Roosevelt's first wife, and Edith was his second, but for the sake of the plot, it has been adapted this way!)
Though Alice wasn't born to Edith, Edith was very fond of Alice. When Theodore Roosevelt was alive, there were several instances when Alice argued with her father, and it was Edith who mediated between them.
Theodore Jr. was also very fond of Alice!
