This website is the work of one man, unrelated to the Farwerck family. The information comes from sources I have access to, which are mostly (semi-)public archives, especially online. Do you have or know about a (possible) source of information not yet used on this website, I’d be much obliged.
If you have anything to add, say, request, etc., you can use the comment field on the page you want to give feedback to.
Should you prefer email: contact [at] farwerck.nl
