Deletion of Mundana Quartet (2nd nomination)

Comment: It is hard to say on this one.  Since I can't read a word of Polish, it is hard to say whether the sources provided fit the criteria of  and .  If a user familiar with Polish can comment on the extent of the coverage in these sources, or in other Polish sources that can be found, a better determination can be made as to whether this group meets the inclusion criteria.  I cannot vote either way though with the information I have, since sources are in fact present
