Throughout the 1850s, there was extensive prejudice against Catholics and Irish immigrants in New England. During their travels throughout Providence, the sisters frequently became targets of taunts and insults. At one point in 1855, a mob marched on the Sisters of Mercy convent in that city. When they arrived at the convent, they found it being guarded by O'Reilly and a group of young Irish men. He told the mob, "The sisters are in their home. They shall not leave it for an hour. I shall protect them while I have life, and if needs be, register their safety with my blood." At this point, the mob dispersed.
