Looking for a Peter Petersen

Does anybody have access to the Ortssippenbuch for Oldendorf by Stade and
the Ortssippenbuch for Ohrensen, Bargstedt?

I am looking for the lineage and if possible the siblings for the following
two people:

I have a Peter Petersen or Peterßen who was born in or about 1701 in
Oldendorf by Stade.

He married Lisabeth Cordts in 1729, and Elisabeth Wichern in Mulsum in 1757.

He passed away on Sept 22, 1771. The online OFB’s don’t list his parents so
I am hoping the Ortssippenbuch may.

The second person I am seeking information on is Wübcke Alpers.

She was born in or about 1757 in Ohrensen which I believe is part of
Bargstedt?

She was the wife of Johann Peter Peters (1758-1836).

She passed away on Feb 18, 1837 in Groß Fredenbeck. According to the
Selsingen Ortssippenbuch, her father’s name was Johann.

Wübcke and her husband Johann Peter Peters had the following children:

Peter (1781), Margarete (1784-1853), Johann (1789), Christopher (abt 1790),
Marie Lisabeth (1792-1796), and Dierk (1799).

The son Christopher married Maria Meyer in Mulsum in 1818 who gave birth to
my GG Grandmother Margarete about 1830.

Thanks for anything anyone can find.

John
