My grandfather Wilhelm MUELLER b 1869 emigrated to the US in 1886. His mother Johanna REGLING was the dau of Joachim Regling and Hanna KOESTER b 1815, dau of Johann Koester and Johanna SCHADE. I'm looking for more information about the KOESTERs and SCHADEs. They lived in Laeven, Meckow, and Labbeescher. Thanks!
