Hal, just so that all your information is accurate:
You've misspelled the name of the town.The correct spelling is Brockum -- there's a "c" before the "k".
Like the U.S., Germany has always been made up of states.We're talking here about what was until 1866 the German state of Hanover (in German: Hannover), the capital of which was the city of Hanover (Hannover).
In 1867, Hanover was annexed by the German state of Prussia (in German: Preussen; capital: Berlin) and became what was to then until 1945 remain the Prussian province of Hanover.
Following World War II and the break-up of the vast state of Prussia by the Allies, the Prussian province of Hanover, the state of Oldenburg, and the two very small states of Brunswick (in German: Braunschweig) and Schaumburg-Lippe combined to form today's new postwar German state of Lower Saxony (in German: Niedersachsen), with the city of Hanover (in German: Hannover) as its capital.
Brockum is a town of about 2000 people today.
You say that Heinrich Klatte's religous denomination was "Evangelisch"."Evangelisch", Hal, is simply German for "Evangelical"!The denomination's name in full is Evangelical Lutheran.In the U.S, too, the denomination is called Evangelical Lutheran.
The church records are of course at the church in Brockum!Here's the contact information:
Ev.-luth. Pfarramt Brockum An der Esse 38 49448 Brockum GERMANY
If the old church records have by chance been sent to the Archives of the Evangelical Lutheran Church of Hanover, they will tell you that and give you the contact information.
You've also misspelled the name of the town where Charlotte Wilhelmine Henriette Lückemeyer was born.The correct spelling is Oppenwehe -- there is no "d".
Oppenwehe is located in what was until 1945 the Prussian province of Westphalia (in German: Westfalen), the capital of which was the city of Münster -- or if written without the "Umlaut" (two dots) over the "u", Muenster -- and the largest city in which is Dortmund.
"Westfalen", Hal, is simply German for "Westphalia", just like "Deutschland" is German for "Germany".
Following World War II and the break-up of the vast state of Prussia by the Allies, the northern half of the Prussian Rhineland or Rhine Province, the Prussian province of Westphalia, and the very small state of Lippe (capital: Detmold) combined to form today's new postwar state of North Rhine-Westphalia (in German: Nordrhein-Westfalen), with the city of Düsseldorf -- or if written without the "Umlaut" over the "u", Duesseldorf -- in the Rhineland as its capital.
Oppenwehe is no longer an independent town.Oppenwehe was one of 13 towns that combined back in 1973 to form a new town called Stemwede.Stemwede is a town of about 14,500 people, of whom about 2200 live in Oppenwehe.
