Why didn't try a search on graftombe.nl?
If it worked for Guitze it is not going to hurt to try to see if you can get results for Aaltje. Did you just copy what I got for Guitze or did you actually do the search on graftombe? Did you get the pictures ordered?
Aaltje is right there.
use last name Terpstra and birthdate between 1905 and 1907
