I found a website that mentions:
"A document I found, about the wedding of his son Blees in 1820 states "Johannes Thur, father of the requestor, died the 15th of October Eighteen hundred two in Genderen That his death can't be proved by any extract in the registers of death, because there aren't any of these registers of that time present at the secretary of Eethen Genderen and Heesbeen. That his grandparents of paternal side have been in Switzerland for several years where these lived and died."
I could not find this document; but I did find other documents:
Johannis Georg Thur and Elisabeth Kuijsten married 1789 Heusden; they had four children:

My ability to read Dutch not excellent; but was able to read "18-nov-1802" in 1821 "bijlagen" and "okt-1802" (no 15?) in 1826 "bijlagen".
I do not see "Switzerland" mentioned in any of the above documents. Did I miss something?
Is anyone able to find any record of "Johannes Georg Thur" before his marriage in 1789?
Thank you for your time, Frank
