In Mary's personal letters....

[Eva Elisabeth]

Toia, I would love to know, too. The following sentence quotes Mary's "My disease is of a womanly nature", and this letter is the only reference Tripp gives for the entire passage. No source for the "damage". The ...part I left out above is "(Tad,) with his especially large head". That's why I wanted to find something (contemporary) about the origin of his nickname as I hoped to find more on the birth in that context.
