I've made a distinction between immigrants & immigrant ancestors in other discussions, but I don't think I conveyed what I meant/envisioned, but now I've created what I was thinking of:
The freespace page http://www.wikitree.com/wiki/Space:New_Netherland_Immigrant_Ancestor_-_Jan_Joosten
When I say "the immigrant ancestor," I mean just one person ... such as Jan Joosten (in WikiTree, Van_Meteren-8) .
My concept is that the subcategory "New Netherland Immigrants from Amsterdam" would include those who left from Amsterdam to settle New Netherland (everyone who took ship, and I suppose chldren born during the voyage). Other "New Netherland Immigrants from ..." subcategories could be created for other ports of embarkation within the parameters of the project. These subcategories will cover everyone who should be under this project but wasn't born in New Netherland.
Then, if all of the New Netherland Settlers had a freespace page for their immigrant ancestor along the lines of http://www.wikitree.com/wiki/Space:New_Netherland_Immigrant_Ancestor_-_Jan_Joosten , then the New Netherland Settlers project page could include a list of those pages or refer to the Category:New Netherland Immigrant Ancestors (no, I haven't done that category yet - I'm about to make another g2g post on that, but I also wanted get feedback on the concept/page before I actually created the category).
I think this would provide an intuitive, clean way to track profiles designated under our project as Project Protected as well as information about the Dutch (non)use of surnames/the use of WikiTree IDs.
I'll be offline till this evening, but I look forward to your feedback (also, I'll respond to any trusted list requests then; please provide feedback on when/if these pages should be open too).
Thanks!
