I haven't seen any tool that does a really good job for organizing new research. For that task you want collections of source material, notes, and speculations which may be tied to an individual, a family, a location, a surname, or other ad-hoc organization schemes.
Existing software is universally bad at the "here's some pieces I'm trying to sort out" research tasks. The organization with research is less based on individuals and their relationships and more on source documents and their contents and associations and interpretations.
