Thanks once again for your help, it is very much appreciated. That certainly take that branch of the family back quite a way! Also, thank you for the links - now I have managed to fill in information for siblings and deaths etc.
On a different note. I am trying to find information for brothers of the Van Den Ijssel family who perished on the Eastern Front in the Second World War. They were apparently buried in Leningrad. Do you know where I may be able to find such information, as I dont know where to start?
