Saint Monica was an Italian christian who was born in 333 and, through the power of persistent prayer and patience, converted her pagan husband and mother-in-law to the Catholic faith. She also prayed for 17 years for her son to change from his life of sin, the boy was Saint Augustine.
Most information about St Monica comes from the writings of her son, St Augustine. He was the eldest of the three children she had with her husband Patricius. The family lived in Tagaste, North Africa, and family life could not have been easy, because by all reports, Patricius was a violent and bad tempered man. He died in 371 when Monica was just 40 and Augustine was a difficult 18 year-old.
