  Large observational surveys, like those that will be conducted at the Vera C.
Rubin Observatory, are expected to discover up to one million new asteroids in
the first year of operation. This will more than double the database of known
asteroids. New methods and techniques will be needed to handle the large influx
of data. Here, we tested some of these new methods by studying the population
of asteroids on stable orbits inside the ${\nu}_6$ secular resonance. This
resonance is one of the strongest mechanisms for destabilizing the orbits of
main-belt bodies and producing Near-Earth Asteroids (NEAs). Yet, stable orbital
configurations where the asteroid pericenter is either aligned or anti-aligned
with that of Saturn exist inside the resonance. The population of stable
${\nu}_6$ resonators is now the largest population of asteroids in stable
orbits inside a secular resonance. Here we obtained the largest sample of
asteroids' proper elements ever used for this problem. Clustering methods and
the use of machine learning algorithms permitted the identification of the
known asteroid families crossed by the ${\nu}_6$ resonance and of two entirely
new groups: the Tiffanykapler and the 138605 QW177 families. The Tiffanykapler
family is the first young asteroid family ever found in a linear secular
resonance, with an age of $3.0\pm1.2$ Myr and an ejection velocity field
parameter of $V_{EJ} = 15^{+6}_{-3}$ m/s. We identify a population of
high-eccentricity objects around the Tina family that may be the first example
of an asteroid family "resonant halo".
