Hello Matthew, You've asked a question about this template. I don't know exactly what the question is, but I can provide some answers.
The template is for use on your profile (living members of Wikitree), not on Noah Jewett (deceased), if you have a Puritan Great Migration ancestor. It's a great way to acknowledge that you have ancestors who were early migrants to New England. I have several. You can see the template on my profile.
To add it to your profile type
{{PGM Descendant|[[Wikitree-ID|name of ancestor]]}}
