Thank you both very much for coming back on this one
While I was unable to search the number references 688c & 701c provided (the
http://www.dutchregiments.org and its successor site appear to have closed down) I was able to find the following further with the info supplied
Regiment Erbach (1690-1720)
Col. Filips Lodewijk Graaf van Erbach
Founded in 1688 as a regiment of Frederick Hartman of Erffa . In 1720 joined Regiment 's Gravenmoer .
Regiment Baldwin (1701-1715)
Regiment Baldwin van Voorst
Col Johan de Jurriën Baldwin,
( † 1710 ) Dutch officer ; major of the cavalry regiment Erbach 1698 ; colonel of a regiment of cavalry Overijssels 1701 ;Brigadier 1704 ; Major General 1709.
The secondary sources for these were cited as:
• Dr . J W Wine , The States Army VIII ( The Hague, 1964 ) ...
• H. Ringoir , pedigrees and continuations of Cavalry and Cyclists ( The Hague, 1978 )
Does anyone have access to these books and know more ?
Thanks again
