Pat,
Ok, maybe I understand now. I also assumed that your free-space page would appear on the WALKER Genealogy page. Some Tagged free-space pages do, but only a few of them. I don't know why there is a limit, but the limit appears to only be 3 or 4.
The fact that some of these links are broken is strange. I have no explanation why they would be included in the list. I assume this is a bug in the WikiTree system. If the broken links were removed your page may show up.
Some of the confusion has been the name of the page called "Walker Genealogy". Yes, that is the title shown on the page, but most(?) people would call it the "Walker Surname Search Results page".
I don't know how to do a search to see everything that is tagged with the "Walker" Tag. If there is a way, I haven't found it yet.
