Hello Roger,
I work on the page www.auswanderer-oldenburg.de. Could you give me your informations about the Vorwerk family in the USA? I would take it for the page. The last generation we take is the generation of the in the USA born children of the emigrants.
A copy of this I sent to Mr. Mählmann who works on the parish records of Emstek.
Best regards,
Gunter (Jüchter)
