Schaumburg split into three pieces (Lippian, Hessian, and Guelphic) after the 1640 death of Count Otto, but the details were not worked out until 1647. The county was never reassembled, although the modern Kreis Schaumburg covers much of the same territory. The Amt structure prior to 1640 is detailed in Studien und Vorarbeiten zum Historischen Atlas Niedersachsens – Google Books and it depicted cartographically in Sachsenhagen – Heimatverein Sachsenhagen Auhagen (heimatverein-sachsenhagen.de) (specifically, the black-and-white map after the entry for 1400—the color map that follows it is not consistent with any other source that I could find). The post-division status of each Amt is cartographically depicted in the Sachsenhagen document entry for 1640 and described in the entry for 1647.
Only three jurisdictions were modified as a result of the 1647 division. Two were Sachsenhagen and Hagenburg, the treatment of which is described thoroughly in the above-referenced document. The other was Vogtei Lachem in Amt Schaumburg. The division of villages is well enough described, but because Lachem itself was assigned to the Guelphic portion, it is not clear what the residual left in the Hessian portion was called. A few sources, including the Wikipedia article on Goldbeck, refer to a Vogtei Rumbeck, so I adopt that convention.
That 1647 status remained stable for over 150 years, with the exception of a few villages that shifted from Amt Bückeburg in the Lippian portion to Vogtei Hattendorf in the Hessian portion between 1722 and 1733. Four of those shifts are documented on pages 32 and 33 of Studien und Vorarbeiten zum Historischen Atlas Niedersachsens – Google Books. The date on which Schermbeck made the shift was inferred from point 12 on page 78. Page 80 of the same source places the date on which Hesse ceded its share of Pohle to Hannover.
The 1817 and 1822 reorganizations of the Ämter in the Hessian portion are described in NLA BU H 120c – Arcinsys detail page (niedersachsen.de). No date could be documented for the shift of Großenwieden from the Weser Vogtei to Amt Oldendorf, but it was after 1821.
