I was think more in terms of a dynamic on-screen display, since I think more people view genealogy data on a web page (or a display screen from their genealogy software). Print is rather too immutable. But certainly, there are a few techniques that would work with print, like those you mentioned. >> I envision a tree display that would display the most likely choice, >> but perhaps if you hovered on a particular link, it might display >> multiple trees overlayed, with different colors or densities based on >> relative likelihoods. > >That seems easy to do in CSS, but I suspect it is like your footnotes: >people are unaware of the other possibilities until their mouse hovers >over a person, fact or relation.

I'm not saying it would be easy though. www.familysearchlabs.org has done some experiments with pedigree and genealogical data display that gave me the idea that some sort of dynamic display might manage to convey this kind of information. I think they use Flash. (But for all that I used to program for a living, I have no idea how any of this web-based programming works. I haven't yet figured out how to design my own home page %^).

I'm not sure exactly what you were trying to do, but it doesn't display correctly in my browser (IE7). The borders and the shading and the text are all somewhat out of alignment with each other, such that I don't know what the intended graphics are. There are two lists of what I presume are offspring (one offset to the right, and one left-aligned and below) which I am guessing are connected to the two wives mentioned in the first box, but that isn't conveyed by the graphics as opposed to my analysis of the text. lojbab

"children" and John Kelly Brown connect together and connect to Benjamin Webb Brown aligned with Elizabeth Vansant, the offsprint below those connect together an align with Lydia Hackett. All the children in the right hand column are connected together and to John Kelly Brown. -- Ian Hotmail is for spammers. Real mail address is igoddard at nildram co uk

Thanks for alerting me to this disastor. One reason I didn't pursue the project is because I had no IE browers (in their various versions) with which to test it. Because MS says it is not much interested in IE development to bring it into conformity with standards, designing a web site that is really cross platform can be a real challenge. I had little reason to tackle it because my aim was only to see if it could be done in pure CSS. -- Haines Brown, KB1GRM
