you could try and post a query to the Breslau/Wroclaw board http://boards.ancestry.com/localities.ceeurope.poland.provin...
You have probably searched these boards here for the surname already? The Search box is on top of each message board page.
Another option would be contacting professional genealogists - some with experience in the field of noble families, like e.g.:
Heraldisch-Genealogische Gesellschaft "Adler"
