Lucy Hale

[RJNorton]

Somewhere, I remember reading that Ella was a petite redhead.

I have seen the "redhead" description, too, but in John Wilkes Booth - Oilman, Ernest C. Miller writes:

"The handsome assassin was also accused of spending considerable time with blonde Ella Turner, originally a native of Richmond, but who had come to Washington and resided with her sister on Ohio Avenue. She is said to have been his mistress for a period of several years."

In his book Roscoe describes her as "strawberry blonde."

The "petite description" seems unanimous among authors (at least in the books I've seen).
