Rehburg & Minden 1803

Hello:
    The marriage record in 1825 from Rehburg Evangelical Church, says my
great great grandfather Ludwig Mackeben was born in 1803 in Minden, son of
Ludwig MACKEBEN and Dorothea WEGNER. In 1825 he married Katharina NORDMEYER
in Rehburg. I have searched the Minden Evangelical church books and could
not find the birth record.
I know the Mackeben surname is found mainly around Rehburg and was told the
surname goes back to the 1600's in that area.

Was there a census for that time period? What historical events were going
on in that area around 1800's as I am trying to determine where else to
look? I know there was some relationship with the town of Eilvese as I have
some old letters from the 1940's and the surname was Wegner but I have not
been able to determine the relationship other than "cousin" as signed in the
letter.
Does anyone recognize the surnames?
I know that Nordmeyer is from the Rehburg area. Kathrina died in 1859 and
Ludwig
married Catharina Louisa Marie DUNKER from Schneeren and had 2 known
children with her. Ludwig died in November 1865 shortly after the birth of
my great grandfather's birth Ludwig.

I know that Minden also referred to a district or kreis that included more
than the town of Minden.
Thanks for the help.
