The remains of an African-American former slave have been moved to a Catholic cathedral in a step towards possible sainthood.

Visitors lined up on Wednesday to honour and pray for the help of Julia Greeley, a domestic worker known for her charity work and evangelism until her death in 1918.

Many touched the glass covering of a wooden chest holding her exhumed skull and other bones. Others placed rosary beads on top of the chest, snapped photos and held up their children so they could view the sacred remains.
