I am looking for information on my grandparents family, Their names were Benjamin & Wupke Oldenburger who came to the US from Nieuwe Schans, Groningen, Holland and settled in Iowa. I know my grandmother came to the states in 1902 with her parents (Frederick & Geertje (Steinhuis) Oldenburger. I don't know when my grandfater came but it was before my grandmother. I know my grandfather's family (Gerrit & Harmke Oldenburger Nee Jansen) sponsored my grandmother's family. My grandmother had two sisters (Trientje & Anje) who married and moved to Minnesota. Their married name was Moerke. I would also like information on the Moerke family.
