i suggest that all warzechas have a common male ancestor in the middle age in silesia. There is a simple opportunity to prove this: test your y chromosome dna. That allows you to place in a certain haplogroup. The majority of warzechas should have the same haplogroup (in my case Haplogroup J2).
I would like to encourage the male warzechas to go to this site: www.familytreedna.com, there you can find further informations..
