We never saw any families at Raven Rock so the Enclave has to have other bases for their non combatants.
Got to keep the gene line and pure and unirradiated after all.
After the destruction of the Mobile Crawler, any married Enclave personal would likely head for their families with the high command gone (again).
And staying in the Capital Wasteland might lead getting stomped on by a repaired Liberty Prime.
Surrendering and disarming might lead to to a terminal case of being lynched or a visit by local raiders.
So there could be a large Enclave remnants with lots of non combatants looking for some place to settle that isn't too close to the CWBoS, the locals doesn't have personal experience with the Enclave, there is enough tech base to keep their gear up, food could be grown, and the noncombatant could be protected.
Likely figure that the Institute would be interested in trading for tech and knowledge.
The leadership might not be "Enclave" any more, but you can't just strip a life time of identity especially after a disaster.
So they would likely still identify themselves as Americans and have a 1950s outlook.
I think it would be a blast that except for a few rogues, all the former Enclave survivors only want a place they can live safely with their families.
You would spend the whole game wondering what they were up to.
I bet we will see some Enclave remnants in the last part of the game.
