The three saints form a triad that is the focus of the annual Obando Fertility Rites held from 17 to 19 May.

Three fishermen, named Juan, Julián, and Diego dela Cruz, were fishing at a place known as Hulingduong in the town of Tambobong (today in Malabon City).

There, they caught the statue with their salambáw, which is a large type of fishing lift net made from bamboo crosspieces and mounted on a raft.

When the fishermen tried to bring the Virgin's image to neighbouring Navotas, their salambáw suddenly grew heavy and immobile.

Spread across the triduum are the Rites, which constitute Masses and processions where devotees of both sexes joyfully dance the fandango in supplication for a child and of good livelihood and harvest.
