the Polands' bearers of the Wilke surname are more likely to trace their ancestry to Germany, not GB.
my point was that this person may not be from poland at all..
It is surname. I found out. It is a family and from Silesia region, border region in Poland with Germany. So, it is quite possible that their root of this family is in Germany as Silesia is mostly Germany origin people in Poland, right? As Wroclaw wrote, there are 282 people with that surname. I wonder if it is one same big family or different families with same surname?
