Notes: This little string of dark nebulae is located a little over three degrees NNE from IC 1396, and about two degrees NNW of the complex of dark nebulae around B 170. B 166 is approximately centered in this image.

I can't find much information on these three, but these descriptions are from the on-line Edward Emerson Barnard  "A Photographic Atlas of Selected Region of The Milky Way":
