Hello Ron,
for Addicks in Oldenbrok I suggest you look at the 'yellow line'
publications of the Oldenburgische Gesellschaft fuer Familienkunde.
Booklet Nr. 9 has a complete list of inhabitants of Oldenbrok of the year
1675 - with several Addicks families. It also shows an Addicks tombstone and
it describes the rules of self-governance of this parish as of 1614.
Booklet Nr. 19 also lists several Addicks families in Oldenbrok as of
1644/1645 as well as other Addicks families in the nearby parishes of Hammelwarden
and Strueckhausen.
