Hi Mark;

The one I marked as "Yours" is PGC 1547827.

The "Unknown" one is north of that and a slight bit west in the last
image.

I found it and a few others using "HyperLeda" Database for physics of
galaxies at:

http://leda.univ-lyon1.fr/

Using a 10 arc minute search radius and PGC 1547827 as a starting point:

http://leda.univ-lyon1.fr/fG.cgi?c=i&z=vg[,,l]&o=dss1:
[B131013.4+181643,10]

you can see several faint galaxies that I picked up there. Supposedly
it's "2MASX J13124494+1803399" or "SDSS J131244.92+180340.8" and here
is a close up view:

TTYL..
