1) I have defined these best practices for my RootsMagic genealogy database:
* Add persons, relationships and facts to my database based on records, not assertions in other family trees
* Investigate record Hints and record Matches from record providers to use, if pertinent, to add content to the tree
* Search for records for my Tree persons in record repositories and in online record providers and use if pertinent
* Use other family trees and other research (e.g., books, periodicals, manuscripts, indexes, etc.) as clues for further research and add if pertinent
* Support Facts/assertions for my Tree persons with
Evidence Explained quality source citations (I tend to use Free form source citations rather than EE-style source templates so that the source citation transfers well in a GEDCOM export).
