Though relatively few in Eorzea, a small number of them have been accepted into everyday life by the other races in the port city of Limsa Lominsa. Others are known to make their home in the region of the Sagolii Desert.

While their overall numbers are not great, their twenty-six tribes are scattered across all reaches of the realm, with small Seeker settlements to be found from the sands of the Sagolii Desert in southern Thanalan to the jagged peaks of Gyr Abania. Yet other Seekers have settled in Limsa Lominsa, drawn to the freedom of pirate life. Many Seekers, particularly those of the younger generation, choose to set off as adventurers, perhaps heeding the same call of the wild their ancestors once heard.

We simply must assume that R'fhul, his sister and parents are/were are simply city-living Miqo'te, despite still following tribal naming conventions and perhaps keeping some connections to their old tribe. Compare the J tribe members in Ala Ghiri.
