There are messages from meirons on different boards about Clarence Pronk! I posted on all the others that "to avoid double searches", etc.....
However, there is one thread that had a response after that:

http://boards.ancestry.com/localities.northam.usa.states.new...

Pretty much what we found as well!
Maybe it is better to concentrate all messages re. Clarence on one board.....

Kind regards,
Marianne
