Jimi, you're record of posting only objects you've observed is still intact -- we took a look at it in your scope back on April 2, 2011! This one is quite easy to find -- just 12' WNW of the bright edge-on NGC 4866.
I'm sure it was on my observing list because GR 8 (another name for UGC 8091) is at the edge - or just beyond - the gravitationally bound Local Group. The name GR 8 comes from the Gibson Reeves, who discovered a number of candidate Virgo dwarfs for his PhD thesis in the mid-1950s (published paper here). It's also known as the "Footprint Galaxy" (not to be confused with Minkowski's Footprint). I believe the nickname may be from Vorontsov-Velyaminov who described the galaxy as the "Imprint of a foot" in the VV Atlas of Interacting Galaxies, Part II (VV 558). It's also included in Zwicky's 8th list (VIII Zw 222) and described as "Post-eruptive, very irregular galaxy with many blue knots and streamers."
