Hello.
I find your post interesting.
May I suggest that you scan / photograph, or copy some how, a page of this tree and send it via the [PM] service to one of the senior people who have posted on your thread. The file, say a jpeg should not be larger than about 300 KB, but that would be enough detail for them to see it's form, and how it displays the information contained therein.
[To reduce the file size only a part page bit, showing layout, or the image put through a down sizeing image processing programme, to create an adjusted, lower resolution copy.]
There would most probably be privacy issues, [and copyright issues] that prevent you going public with the actual table.
All the proprietary tables have their own unique identifiers, and once recognized, that would allow the search to be focused on users, and their holdings in that system.
Just a thought.
May not work, because the only 20 page one I've got after 35 years of research, is my own generated Excel spreadsheet trying to tie in two big main branches starting in Scotland in the late 1790's but missing the all important OPR to confirm the link we know is out there, and the "family tree" with the most names on it [in the thousands] is a hand drawn circle radiating out through nine generations. So the above advise would not count.
