Despite not being technically Slavic, Lithuanians and Latvians seem closer genetically to Russians and to East Slavs than Polish people are. Poles have significant Germanic influence.
As I remember I chose only those with LAtvian/Lithuanian names and surnames.
Why would it have to be Germanic? Unetice in Poland was already Polish like.
I guess Poles have some of the Germanic clade of R1b but that can still pre-date Germanics.
