The History of the Donner Party - Charles Fayette McGlashan

Eleven children were born to them, and four are now living. One of these, Lillie, now lives in Sacramento with her husband. Another, Paulina, a widow, resides in San Rafael. Bertha and Augusta live with the father at Brighton, Sacramento County. Both these children are hopelessly idiotic. Bertha is twenty-six years of age, and has never uttered an intelligible word. Augusta is fifteen years old, weighs two hundred and five pounds, and possesses only slight traces of intelligence. Teething spasms, occurring when they were about two years old, is the cause of their idiocy. Both are subject to frequent and violent spasms or epileptic fits.
