Hi Darlene, I don´t know very much about the meaning of the arms, because the simbols of polish arms have different meanings compared to western european arms. The star in the middle is called in german "Drudenfuss". It should save against evil ghosts and it stands for luck. I gathered my informations from several essays of Mr. v. Schmude at the university of Dortmund. Mr. v. Schmude is also relatet to that family. He wrote a lot about Trzebiatkow, which was called in Prussia "Radensfelde" and about the polish nobility. I also got several informations from a book about noble families in Prussia. I hope, this is usefull to you.
Yours Matthias
