I disagree. One "yes" would be dishonest and misleading, since I disagree with the three major aspects of this topic.

Really, it's just unwise, and probably unfounded, to try and reduce the creation of M-E to a handful of shared attributes between three female characters and the fact that Tolkien never had a sister. There were a huge amount of things in Tolkien's life experience that we can reasonably assume had a hand in shaping Arda, and to try and pin it all down on just this one thing seems a little silly.
