The collection contains materials reflective of Portuguese cultural and Catholic traditions like the Sociedad da Irmandade
do Divino Espírito Santo (I.D.E.S.) (Society of the Divine Holy Spirit), and the Festas do Espírito Santo (Festivals of the
Holy Spirit). Included in the collection are Materri's historical research notes; copies of local newspaper articles from
The Westside published in Newman, California; and original photographs. The collection also includes Materri's personal worship
items from when she was a child; and textile garments made by Materri's mother, including the cape she wore as the Queen of
the Holy Ghost Festival (c. 1920s) and her First Holy Communion outfit.
Nydea Gloria (Azevedo) Matteri (b. 195 d. 2006), was born in Madera, California, the daughter of parents who emigrated from
Saint Jorge Island, Azores, Portugal in 1911. Matteri's family attended Saint Joachim Catholic Church in Newman, California,
one of several churches in the San Joaquin Valley serving a predominately Portuguese Catholic population at that time. Several
Azorean Catholic traditions were observed in these parishes, including the Holy Ghost Festa, which Materri was crowned its
Queen in 1929. Matteri began documenting and preserving Saint Joachim Church's history and the local Portuguese-Catholic history
while she served as an employee of the parish and volunteer.
