@Eric Shulman Great, that works, thanks! Really minor follow-up question. What do I have to put before [field:father-id{!!id}] to get it to actually show up on the page as text and a link?
Currently, I can do this: <<list-links [field:id{!!father-id}]>> (which is the inverse, for finding fathers as opposed to finding sons) but that produces a list e.g. - Robert Smith I just want it to show Robert Smith Because people only have one biological father! I think the <<list-links>> bit is a 'macro'? I've tried: <[field:id{!!father}]> <<[field:id{!!father}]>> <<$link [field:id{!!father}]>> <$link to=[field:id{!!father}]>[field:id{!!father}]</$link> All with no luck. Slightly more general question, I've found myself a bit baffled by macros/whatever they are. TiddlyWiki as loads of examples of operators, but unless you know what you need to put before them, they aren't actually usable! For example, I know the subtract operator looks like this: [[23]subtract[19]] But obviously, just putting that in a tiddler doesn't produce the value "4", you have to put something before it. I've got no clue what that should be, and the code actually used in the wiki: <<.operator-example 1 "[[23]subtract[19]]">> Does not work. Sorry to dump loads of questions! I just get the impression that TiddlyWiki is incredibly powerful and perfect for my use-case, but there is a lot of basic syntax stuff that I just don't get.
