In case anyone is interested, I have found a way to clean-up my gedcom files. I use the anniversary list that comes out each week. I change those that need updating each week, usually about 5 or 6 family members of the 50+ that I manage.
I copy much of the basic items from my gedcome source and write a few lines for the Biography, and at minimum the FAG source along with a few pictures.
This will still never be completed as my Ancestry Tree was started many moons before I discovered WikiTree, but it is getting there. The watchlist in my case has far too many non-family members
Dar I list just one? [[Schindler-294|William Schindler]]
