It's cute how the Help:Pre-1700 Profiles page says if there isn't a pre-1700 project that applies to the new pre-1700 profile I just created, "it's unfortunate." Then they don't go on to say what to do about it except "ask advice," hinting that if there's no project maybe no one will answer?
I did my due diligence and convinced myself that the existing profile on WikiTree that most closely resembled my target [[Layton-1846|Andrew Layton]]-1846 (1698 - 1765), namely [[Layton-380|Andrew Layton]]-380, actually belongs to the next older generation. WikiTree seems to have a hole just the size and shape of the Andrew Layton whose Bible records appear in my new Free Space Profile, [[Space:Layton Bible Affidavits|Layton Bible Affidavits]].
Unless I'm behind the times, there isn't a project that covers this yet. I expect the upcoming New Jersey Settlers Project might apply, depending what the final scope of the project is chosen to be. So meanwhile I'm "trailblazing" as the Help page calls it, and you pre-1700 experts might want to take a look at my work.
Look Ma, no GEDCOMS.
