Whew. Just finished updating the list of Gateways on the two category pages - Bigod-1 Descendants (Hugh) & Bigod-2 Descendants (Roger). The combined page that Brian referenced was too cumbersome to maintain, so it has been deleted (actually, merged away into another page slated for deletion, which itself will probably be merged away into a private, non-project page or deleted).
If you check your relationship to either Hugh or Roger,* you can then check for matches with Gateway names on the Descendants category pages for someone born late 1500s/pre-1700 in the returned trail. For example, my trail goes through an immigrant ancestor born in 1623 who is (sadly) not a Gateway ancestor recognized by Richardson or the Magna Carta Project.
* To get a relationship trail, you can plug in Bigod-1 or Bigod-2, respectively, at [Special:Relationship], or click the "Relationship to Me" link in the dropdown menu under Bigod-1 or Bigod-2 in the mini-menu at upper right on their profile pages.
In February, I plan to check through the profiles on the badged trails, but I think they've already been added to the appropriate categories. This means that if you click "[Limit to Watchlist]" on one of the Descendants category pages, you should get an accurate list of any profiles on your watchlist that are in a badged trail to Hugh or Roger (depending on whose category page you're on - Roger has a few more trails than Hugh, since not all trails from Roger went through his son Hugh).
Note that the Descendants categories are a profile management tool for the Magna Carta Project and only include profiles in a trail badged by the project, which only means they only run from Gateway to Surety Baron - no children/descendants of Gateways & no collateral relatives.
Cheers, Liz
