I added the PhpGedView application to the site and have uploaded family history data for several generations of Christian Stauffer's (1711) descendants. Take a look at Christian Stauffer Donegal
Surname groups can work on editing a common family GEDCOM file. Start a conversation with me by clicking here and I can set up your userid on the PhpGedView pages.
There is also a link on the Stauffer Group page in the Common Links area
Please experiment on those pages and let me know what you think.
