Cemetery Without Crosses/The Great Silence

Howdy Y’all,
This is my first post so please forgive me if I am asking a question that may have been discussed in the past.

I was watching Cemetery Without Crosses again last night and I noticed someting that someone on this forum may be able to answer.

Does anyone know if Vonetta McGee (of The Great Silence) dubbed the voice of “Maria” (Michele Mercier) on the English language track of Cemetery Without Crosses? It sounds like her to me.

These are two of my favorite Spaghetti Westerns.
