That's great, Andy!
You could just add to that as you go long if, for example, you find information about a family residence. Or you could share information about the town they lived in, etc. That way, you could link to this page from any profiles that were connected to the information.
I'm sure others will have creative suggestions, too. :-) Actually, if you want more feedback on how to use the FSP that you created, you could post a separate question in the forum specifically asking for that. It's more likely people would read that than a thread they're not involved in already.
re: linking in G2G vs. linking on a profile or FSP ... G2G and the part of WikiTree where profiles live are actually two different pieces of software. So, G2G doesn't work at all like the free-text areas on profiles. G2G works more like a traditional website or forum and doesn't use wiki markup.
