Michelle,
I've done some searching and found some info that you may already have.
Here's a shiplist with three Sprengelmeyers from 1867
ISTG Vol 4 - Bark Clara
They(George, Anna Marie and Franz) are all listed as coming from Gland.
I don't find any town by that name so I presume it refers to Glane. They are
listed In the Osnabrück emigration archives:
Sprengelmeyer, Anna Maria 15977 Laer
PERS Sprengelmeyer, Anna Marie Gertrud 13555 Glane
PERS Sprengelmeyer, Anna Sabine 13883 Hagen
PERS Sprengelmeyer, Bernhard Heinrich Christoph 13556 Glane
PERS Sprengelmeyer, Cathrine Marie 13883 Hagen
PERS Sprengelmeyer, Elisabeth 13557 Glane
PERS Sprengelmeyer, Elisabeth 15975 (1865) Laer
PERS Sprengelmeyer, Franz Heinrich 13558 Glane
PERS Sprengelmeyer, Friedrich 23091 St. Johann (Harderberg,
Holzhausen, Malbergen, Nahne, Voxtrup
PERS Sprengelmeyer, G. Heinrich 14201 Hagen
PERS Sprengelmeyer, gerhard Heinrich 13883 Hagen
PERS Sprengelmeyer, Jo= 13883 Hagen
PERS Sprengelmeyer, Johann Heinrich 15977 Laer
PERS Sprengelmeyer, Johann Heinrich 23091 (See Friedrich)
PERS Sprengelmeyer, Johann Hermann 15976 Laer
PERS Sprengelmeyer, Johann Theodor 23092 (see Friedrich)
PERS Sprengelmeyer, Maria Elisabeth 13956 Hagen
PERS Sprengelmeyer, Marie Catharine 13558 Glane
PERS Sprengelmeyer, Marie Elisabeth 13883 Hagen
PERS Sprengelmeyer, Marie Elisabeth 23091 (see Friedrich)
PERS Sprengelmeyer, Marie Elisabeth Catharine 13883 Hagen
PERS Sprengelmeyer, Mathias Heinrich 13558 Glane
PERS Sprengelmeyer, ohne Vorn., weibl. 14199 Hagen
PERS Sprengelmeyer, weibl. 14200 Hagen
These towns are all around the area south of Osnabrück.
I found marriages in the St.Louis church records:
http://genealogyinstlouis.accessgenealogy.com/dettleff-marr1869.htm
Joseph Sprengelmeyer married Anna Marie Peitz June 1859. His brother
Matthias is listed as a witness. Caspar and Marianne Sprengelmeyer are
Joseph's parents.
Then, somewhere it says that August Sprengelmeyer and Johanna are not listed
but they married Apr. 23, 1869.
That means the George Sprengelmeyer(emigration 1867) came AFTER August.
That may mean that they are brothers or certainly cousins.
Keep track of every Sprengelmeyer name you see from that area south of
Osnabrück. Probably, they'll all tie together sometime. August is not
directly in the emigration archives--or he may be listed with another name.
It was common for people to have 2-4 names before the surname. One can't
always know which one they usually used for themselves. Often it is the
last of the names listed before the surname.
By the way, Osnabrück was in Hannover kingdom. Prussia overlapped as
well in certain areas.
