things to be confirmed before anyone can research anything anywhere:
1. original spelling of the surname in the native language of your ancestors
2. original spelling of the surname for the period when your ancestors were born in their place of origin ( this will in many cases differ from 1. due to foreign languages that were used as official language)
3. ethnic and religious affiliation of your ancestors
then you can proceed to
4. trace the family within the vital and other records in the community of origin for as far back as they exist
5. trace the surname/family/clan/community through earlier migrations and origin in historical sources
It is always a nice chapter of family and surname history to document all places around the globe where it is found.
