Call the Midwife Wiki

Sister Monica Joan O.S.R.N (birth name, Antonia Keville) was one of the first to qualify as a nurse midwife in the United Kingdom. She is portrayed by Judy Parfitt.


Sister Monica Joan was born in a grand estate, and was born into a very well-to-do family who didn't approve of her pursuit of a midwifery career nor did they support her in her subsequent entry into the religious life. Her difficulties with her family have been referred to frequently throughout the series although she does reconcile with her nephew and his family in Series Two.

Young Antonia Keville

As a young girl. Sister Monica Joan, then named Antonia, was well educated and found solace in reading books, particularly the Bible. She also loved sweets very much. Antonia had a very difficult relationship with her mother, the reasons for which are not explained fully, but it is hinted that Antonia's interest in religion and desire to become a nurse contributed to the strain. Later in life, Sister Monica Joan recalled that her mother would call her "stupid" and say she was "too tall". She would go on to say that their tumultuous relationship "did not grieve" her when her mother was still alive, but once she died, she found that she missed her dearly, and still loved her deeply, despite their differences.

First vows-married to Christ

When Sister Monica Joan entered into the religious life she had not a penny to her name, perhaps because her family disowned her. In Series 5, she recalls that when she took her final vows and had to wear a wedding dress to commemorate the day, she was deemed too tall to have need of high heels. When her mother died she left her some of her jewellery which was given to the Order when she took her final vows in 1904. These were the jewels that Sister Monica Joan was accused of stealing in the Series One finale but Mother Jesu tells the court she gave her the jewels as "balm for an old wound". Later, during a time when the Sister was very confused and upset, Sister Julienne brought out the jewels and grounded Sister Monica Joan back to her surroundings, calming her greatly.


Sister Monica Joan has a love of literature, astrology, and sweets, particularly cake. When Jenny first arrives at Nonnatus House, she is quick to show off her love for astrology, and to insist that Jenny consume a whole cake with her. She has a habit of consuming any cake she can get her hands on, leading to the other nuns and midwives trying to hide them from her, but she somehow always manages to track one down, telling Jenny that she is "attuned to feel vibrations".

Due to her old age, Sister Monica Joan often gets confused. At the end of the first season, she is taken to court for theft, and during this time, some jewellery is found amongst her belongings, but it turns out the jewlery had belonged to her mother, and Mother Jesu told the court that Sister Monica Joan recogzised neither the jewels nor her petty thefts due to her fragility, and the charges were dropped.

Despite her poor memory, Sister Monica Joan has moments when she remembers things very clearly. One such instance was in S06E05 when she recognized Nonnatus House's newest midwife, Valerie Dyer, and remembered all the details of her birth as if it happened yesterday: Sister Monica Joan recalled that both she and Sister Evangelina attended to Valerie's mother, that Valerie was the second of three daughters, and she remembered cutting Valerie's umbilical cord.

In the 2013 Christmas Special when Shelagh prepares for her wedding to Dr. Turner, Sister Monica Joan expresses sorrow at having lost Sister Bernadette. She speculates that Shelagh threw away a life of religion for the pleasures of physical love, "confusing" what she was truly in need of. Sister Julienne calms her down, saying it is normal to miss their Sister, but that they must respect her choice. At the end of the episode, Sister Monica Joan gives Shelagh her prized hyacinth flowers to walk down the aisle with.

In Series 5, when Sister Evangelina passes away, Dr. Turner tells Sister Julienne that because the Sister died suddenly and unexpectedly, there will need to be an autopsy. Sister Monica Joan was devastated at the prospect, saying that to do an autopsy would "maim" Sister Evangelina for all eternity. Thankfully, the autopsy did not occur.
