[Ger-Poland-Volhynia] German migration to Poland?

[Beth Burke]

I've been following the conversation regarding German migration to Poland,
and although interesting, it also has me a bit confused.

My family (both sides) came from the areas surrounding Lublin, Poland, to
include Chelm and Dubeczno.  They weren't necessarily born there, but many
of the written records state Lublin and I can also remember my grandparents
using the name Lublin often.  

I'm confused as to what "area" Lublin falls into.  Yes, it's in Poland, but
it's clearly not Volhynia because it's not far enough east.  

There is a German settlement map at the following website:

Using this map (or others) only tells me that Lublin was in Poland, it
doesn't tell me whether it was a part of another named area over the
hundreds of years that Lublin and surrounds were passed back and forth.

Anyone who can educate me about this is free to do so.
