Family tree is the most incredible database and I appreciate all of the work that you are doing on it. It is so much superior to the ancestry trees or anything else out there that there is no comparison. I find it particularly impressive in finding overlooked members of the family and finding and resolving errors that have krept in. I have developed a system of organizing the sources that facilitates evaluation and analysis of the sources but wish that there was something built into the system that would do this same work.
I first all all sources that I can find that refer to this individual from FamilySearch Records and add as appropriate records from groups which are not just duplicates of a record which is something already found from Family Search Records.
Next I create a banner source to split thee list in two and make sure the sorting is in the custom mode. Then I sort the sources leaving 1 copy each of each key document providing information on that individual in the upper portion and leaving all duplicates of a document, or documents where the individual is only mentioned as a parent or other in the lower section. Next I organize the upper section chronologically.
The resulting upper list highlights data gaps and data conflicts which allows me to concentrate efforts to find missing evidence and resolve mistakes that have krept in. It also make it easy for those that follow to review and evaluate the work that I have done and add to it.
