I'm not related.
There's now a lot more information on the internet then back in 1998 so I don't know if you are still seeking more information.
Looking at your message of 1998 I noticed that you have as parents of Theodora Margaretha Zoutendijk : Ijsbrand Zoutendijk and Margaretha Delight ?
I don't know your source but I think she was a daughter of Margaretha Johanna Zoutendijk and her father is unknown.
See for example the mariage-record of 24 April ( not 27 April )https://familysearch.org/pal:/MM9.3.1/TH-1-10796-97223-27?cc...
