Hi VLD549, interesting question.
First of all: did I add ‘Schauselbroek’ ? I have no recollection, but could be wrong.
There are many references for both Schauselbroek (Atlas des chemins vicinaux 1841, Popp 1842-1879, Vandermaelen 1846-1854, NGI 1969 & 1981) and Schouselbroek (NGI 1904 & 1939). The oldest one I found (Atlas des chemins vicinaux 1841) is Schauselbroek. I also found one reference for Schonselbroek (NGI 1873).
Therefore I opt for Schauselbroek, but will add the alternative names.
Best regards,
Tom
