Reception_oh_Jews_in_Poland_1096

I’ve just started looking into Polish history because of a cookbook I received as a gift for Christmas.  I cam across this picture while looking up Boleslaus the Wrymouth on line.  I like the picture a lot, very colorful.  But the name, Boleslaus the Wrymouth, really intrigued me.  I can’t help wonder if he is a distant ancestor, or are we all sort of wry in the mouth..?
