Eszrerninken, Kreis Labiau, OstPreussia

Hello,

I'm excited to find town of Popelken in recent messages. My ancestors came
from a village near Popelken named Eszrerninken [think correct spelling?].
Church attended would be Popelken?
Surnames from area are:
Schlitzkus
Kadereit
Reich

Thank you for your great information
Marie
