Joanna Mercedes Alessandra Sturm

Notes:

She is is a great-granddaughter of 26th U.S. President Theodore Roosevelt and the granddaughter of Alice Roosevelt Longworth. Left an orphan at a very young age, custody of Joanna was granted to her grandmother, Alice Longworth who doted on her granddaughter and the two were very close.

In the past thirty years, six books have been written about Alice Roosevelt with Sturm being a significant cited resource.
She has provided historical information and insights into the world of the Roosevelts of Hyde Park and Oyster Bay to virtually every Roosevelt biographer of the last thirty years, and she is credited by almost every professional TR biographer since 1970.
