I am looking into my family tree (Bireta). The Biretas are from Budykierz Poland. This is where my grandfathers family are from. This is a small village not far from Warsaw. This village comprises mainly of the Bireta and Kulesza families. As I understand the Kulesza married into the Bireta family. My mother told me that the land in and around Budykierz was all owned by the Biretas. There are still Kuleszas living in Budykierz.
