DNA of Iłowiecki

The family of Iłowiecki lived in the medieval times just beside the family of Błociszewski. It was therefore presumed that both families are related but only through marriage. The haplogoups are very different as Błociszewski show west slavic origin and R1a while Iłowiecki show R1b - western european group. It is therefore presumed that Iłowiecki family joined Ostoja in the begining of the Piast dynasty and origin from Germany.
