Re: Wolverines, we have a canon story that a remnant survived the final naval battle by being elsewhere on picket duty, and headed for the Inner Sphere, while another subgroup fled the final battle and struck off on its own with Steel Vipers in pursuit.
Based on what's been hinted in various sources, the implications are as follows (your mileage may vary):
1) Picket Fleet #1 and #2 reunited with a late-arriving ship of sibcadets and became the Minnesota Tribe, raiding the Combine to replace their lost civilian caste members. This group circumnavigated the Inner Sphere and near Periphery going clockwise until it reached a spot rimward of the Magistracy of Canopus. Sometime around the 2010s, they opened limited relations with the Magistracy, trading technology (particularly medical tech) in exchange for intel on the Inner Sphere. At some point they abandoned their first base world for unknown reasons, and may have blended into the Magistracy. They have had a working relationship with the Ebon Magistrate, and may have had a role in its creation. (Trish EBON was the head of the Wolverine Watch.)
2) The Zughoffer Weir and two support ships appear, based on circumstantial evidence and elements of the mostly fraudulent "Wolverine Journal," to have been found by ComStar while still in the Periphery, and were brought into the fold. The Zughoffer Weir did end up in the Word of Blake fleet. And someone fed highly specific intel to the Primus about the Clans (attributed to prophetic nightmares) that resulted in the creation of the Explorer Corps.
3) Picket Fleet #3 appears to have founded a settlement within transit range of the massacre site where most of the Wolverines died, since someone keeps coming back centuries later to lay flowers on the empty grave of Sarah McEvedy.
