The Susanne van Soldt Manuscript is a keyboard anthology dated 1599 consisting of 33 pieces copied by or for a young Flemish or Dutch girl living in London.
Hans probably took refuge in London after the sack of Antwerp by the Spanish in 1576, and Susanne was born there and baptized at the Dutch Church at Austin Friars on 20 May 1586.
Alan Curtis could have been easily confused due to the fact there were at least three Johannes or variants Hans, Jan, and John in London during this period of time.
The written van Soldt family history copies are kept at the Central Bureau voor Genealogie and at the Groen Hart Archives.
While most of the pieces, including the psalm settings, are anonymous, many of the Franco-Flemish dance tunes can be found in other collections of the period, notably the Dublin Virginal Manuscript of circa 1570.
