Many kind and thanks for the responses.
Out of curiosity I spent some time trying to zoom as much as I could on the "belt," and there appears to be an image of one (possibly two) men on a horse and I can just about make out a word that looks like "Trinity."
I say the lady is not related, but I have thought that about others in the album, only for them in time to eventually turn up on the tree. So I shall keep searching for her and see what turns up.
