The Holy Martyrs Speusippus, Eleusippus, Meleusippus, and their grandmother Leonilla together with Neon, Turbo and Jonilla suffered in Gaul (by another account, in Cappadocia) in the second century, during the persecution under Marcus Aurelius (161-180).
These martyrs are particularly revered in Spain, where many churches are dedicated to them. The relics of the holy martyrs were given by the Byzantine emperor Zeno to a French nobleman from the city of Langres, where they now rest.
Troparion - Tone 4
Your holy martyr Speusippus, O Lord,
Through his sufferings has received an incorruptible crown from You, our God.
For having Your strength, he laid low his adversaries,
And shattered the powerless boldness of demons.
Through his intercessions, save our souls!
