Hi Kevin,
can be identified if this sword was a Heavy Cavalry sword (straight) or light cavalry (curved)? Also, is it a trooper's sword (brass used in the guard and simply laid out) or an officer's blade (often more decorated)?
There's 2 ways to go about this:
There's a Dutch Cavalrymuseum in Amersfoort, which has a website at:
www.cavaleriemuseum.nl
They might be able to dig something up for you, but many Dutch Military Museums have only a limited library.
And then there's the Dutch National Archives, somewhat like the Public Record Office at Kew in Britain. They have the regimental Rolls for the period, and can also be contacted through their website at:
www.nationaalarchief.nl
The Archive-pieces you're then interested in are:
2.13.09 - Ministerie van Oorlog: Stamboeken van Onderofficieren en Minderen van de Landmacht, 1813-1924
2.13.04 - Ministerie van Oorlog: Dienststaten en Stamboeken Officieren Landmacht en Koninklijk Nederlands-Indisch Leger (KNIL), (1813) 1814-1877 (1923)
2.13.06 - Ministerie van Oorlog: Dienststaten en Stamboeken Officieren Landmacht en Koninklijk Nederlands-Indisch Leger (KNIL): Naamindex Officieren Landmacht: Ju t/m Z
Good luck!!
