Here is a link to quilt images:

My great grandmother made this in 1875. As you can see by the bottom photo, it isn't on a diagonal like the quilts in the link in an earlier post. This is probably just a variation, but the pattern of the dark pieces looks much the same as the pattern being discussed.

(There are a couple of other images stashed here also, an odd dove print and my cat Clementine).
