Hi Marlene,
thank you for your informations!
We can't take your Daniel family for our database because the emigrating people were born in the former Kingdom of Hannover and not in Oldenburg.
The Gustav Adolph Gerdes we have in our database. But we have a source from our state archive that he emigrated in 1889 after the death of his parents. Our problem is that we are still working on the church records of Oldenburg. So I have no informations about Gustavs aunt and her husband. Therefore I sent a copy of this email to Mr. Ahlers who have some informations from the church records of Oldenburg.
Best regards,
Gunter
