The Larkinsons maintained an extensive and detailed personnel database. This was pretty much standard practice among many organizations.
None of them wanted to lose track of their own people. That would be stupid and potentially dangerous as the ones they neglected might turn into spies or saboteurs without their notice!
Keeping track of people's movements, actions and other parameters was much easier when they spent most if not all of their time aboard starships that were fully under the control of the respective organization.
The Larkinson Clan recorded more information about its people than normal. Its patriarch was a bit paranoid and valued his ships. The outbreak of the Crown Uprising had spooked him quite a lot, causing him to push for greater monitoring and tracking.
