For 14th -15th Century Ancestors we should only use copies of Original Baptism Records, Probated Wills, Burial Records, etc. for a source. Not copies of online ancestry trees, They're not a documented source, a waste of space for our Geni.com profiles.
Personally find it annoying when clicking on Sources Tab and finding only a series of connected online ancestry trees. We really need to work on actual documentation, it is available to upload. Then we can review together to be sure we have it correct.
