Caldey Island: 6-year-old who drowned in 1977 was victim of abuse, says sister

EXCLUSIVE by Amanda Gearing
A WOMAN whose sister drowned off Caldey Island in 1977 as a 6-year-old child says they were both sexually abused by a monk there.
Father Thaddeus Kotik, who lived at Caldey Abbey for 45 years before his death in 1992, is accused of abusing several girls in the 1970s and 1980s.
Joanna Biggs, 48, is the first of Kotik’s alleged victims to waive anonymity to speak out about her ordeal. She has revealed that is well as being victim to sexual abuse – her sister was blamed for her own death.
Reading the shocking revelations that a monk had abused several children on Caldey Island in the 1970s and 1980s broke open a kaleidoscope of traumatic memories for Joanna Biggs.
Memories of abuse by Father Thaddeus Kotik of herself and her younger sister, Theresa; memories of the last day she spent with Theresa playing on Sandtop Bay on Caldey Island; memories of a grey nun’s veil blowing in the wind and the panicked look on the nun’s face when Theresa was swept out to sea and drowned on 18 July 1977.
Joanna Biggs told her siblings about the abuse in recent years but she has now also told her grieving parents of her abuse by Fr Thaddeus and that their daughter who died was also a victim of abuse.
Joanna Biggs has been affected by the abuse herself – not being able to drink milk for decades because of the smell that reminds her of the dairy where the abuse happened.
But it is the drowning of her younger sibling Theresa that has compelled Joanna Biggs to research the facts surrounding her sister’s death and to publicly defend Theresa’s honour against what she believes to be false evidence given to the inquest.
A nun, Sister Sheila Singleton, who was caring for a group of children at the beach on Caldey Island, claimed in evidence that she had forbidden Theresa to swim and that Theresa had disobeyed her by going in the water.
“This is not true,” Joanna Biggs said. “The nun asked me to help her blow up Theresa’s armbands so I showed her how to do that.”
“[The nun] helped put Theresa’s armbands on. And then she said ‘off you go’.”
“My sister was not naughty. I was told she was found with one of her armbands on.”
Theresa’s father John Biggs strongly supports Joanna’s desire now to have the truth revealed in the hope of bringing a proper closure for the family over his daughter’s death.
John Biggs said he and his wife “never believed that Theresa wilfully disobeyed but were not there to prove it”.
Joanna Biggs said her parents had lived with the nun’s lie for more than 40 years. “It is time for my sister to be released from false blame,” she said.
“My sister was more adventurous and more assertive than me,” she said.
Even at six years old it was Theresa who made sure that they escaped further abuse by Fr Thaddeus, she said.
“My sister made a pact with me that we would never be alone with Fr Thaddeus even if he offered us sweets.”
After speaking with her elderly parents, Joanna Biggs searched the Pembrokeshire Archives to unearth the inquest file that her parents had always been too traumatised to read.
Theresa’s father attended the inquest but her mother, who had a very young baby at the time, was not able to attend.
The inquest documents show the drowning was investigated in one day and the inquest was held the following day, just two days after the drowning.
At last answers are being found. Joanna Biggs is now determined to correct the record so that her little sister can be remembered as the obedient child she was raised to be by her devout Catholic parents.
Sister Singleton did not give evidence in person but she made a statement to the court claiming that she “told Theresa she was not to go into the water as it was too cold” and that Theresa had disobeyed her direction and went swimming without permission.
Sister Singleton said she saw Theresa “going towards the water” and asked one of the boys to look after her.
“It seemed only minutes had passed when some of the boys shouted [to] me. I understood something had happened to Theresa,” Sister Singleton wrote.
But teenagers at the beach gave evidence that the nun had allowed a large group of children to swim in a force 5 to 6 gale at a beach with dangerous ocean currents, put floaties on Theresa, 6, led her to the water’s edge and asked a boy of 14 to look after her in the water.
A boy of 14, James Donnelly, gave evidence that Sister Singleton had made her way towards him with Theresa – who was wearing inflated armbands – and asked him to take the girl down to the water.
James Donnelly told the inquest that he went in the water with Theresa, leaving her playing in shallow water while he went out to deeper water.
James lost sight of Theresa, saw that she had been swept into deeper water and tried to reach her with help from another boy, John Lewis, 12, who had come to help.
John reached her and Theresa held onto him and told him “Don’t let go of me”, but he said she was pulling him under the surface and they were both swallowing water.
John said he pushed the girl’s arms away so he could get out of the water and get help.
Theresa was swept further out and was waving her arms and screaming. Another boy, Anthony Bonar, 15, swam towards her but could not reach her because the current was too strong.
By then Anthony said he could only see two orange armbands floating on the water and the girl’s arms waving in the air.
“Her head was under the water,” he said.
The coastguard was called and retrieved the girl’s body. A doctor who met the rescue boat at the slipway pronounced her dead.
The coroner accepted the nun’s evidence over that of the three boys.
Theresa’s family would like to see the inquest re-opened so that the evidence of the boys can now be accepted and so the brave efforts of the boys to save Theresa can be recognised.
Joanna Biggs has also confirmed that a group of monks was standing on the rocks praying.
“None of them gave evidence to the inquest,” she said.
In addition, the abbot of Caldey Abbey and a parish priest Father David Bottrill were on the island at the time.
“I know that the abbot rang our home and told my father that Theresa was dead,” Ms Biggs said. “My family has only just become aware that there were monks present on the beach.”
What still weighs on Joanna Biggs’ mind after 40 years is that three boys battled dangerous swell and undercurrents to try to rescue a child while adults on the beach and on the rocks did not give practical help.
“This was a heavy enough burden for these children to carry for the rest of their lives. But on top of this, there was no mention in the inquest about the actions of the adults who were present that day – except for the false statement of Sister Sheila,” she said.
“Questions need to be asked – Why were any children at all allowed to swim on such a dangerous beach that day? Why did no adult enter the water to try to assist the boys?” she said.
Joanna Biggs also questions why no adequate warning signs about dangerous tides were erected before or after her sister drowned.
“Whenever my family visits my sister’s grave on Caldey Island it distresses us to see there are still no adequate warning signs of the dangerous underwater currents at Sandtop Bay,” she said.
The Herald sought comment from Sister Singleton but the Irish religious order to which she belonged, the Congregation of the Little Sisters of the Sisters of the Assumption, has confirmed that Sister Singleton died in 2004.

St Davids Cathedral strengthens spiritual ties with St Patrick’s Cathedral in Armagh

THE DEEP spiritual connection between Wales and Ireland was celebrated this St Patrick’s Day as Dean Sarah Rowland Jones of St Davids Cathedral presented prints of the icons of St David and St Patrick to Dean Shane Forster of St Patrick’s Cathedral, Armagh (Anglican, Church of Ireland).
The presentation took place after Dean Sarah delivered a sermon at the St Patrick’s Day service in Armagh, where she spoke about the shared Christian heritage of the two patron saints and their enduring influence on the faith communities of both nations.
A legacy of faith and unity
St David and St Patrick, both pivotal figures in the early Christian church, played key roles in spreading the Gospel and establishing monastic traditions. Their legacies have continued to shape the spiritual landscapes of Wales and Ireland for centuries.
Dean Sarah reflected on these historical connections during her sermon, highlighting the common themes of faith, devotion, and service that unite the two saints. She also shared the last recorded words of St David with the congregation:
“Be joyful, keep the faith, and do the little things.”
“Byddwch lawen, cadwch y ffydd, a gwnewch y pethau bychain!”
These words, spoken by St David in the 6th century, remain central to the ethos of Welsh Christianity, encouraging believers to find meaning in small acts of kindness and faithfulness.
A symbolic exchange
The exchange of icon prints between the two cathedrals served as a symbol of ongoing friendship and unity between the Welsh and Irish Anglican communities. Both cathedrals hold significant historical and religious importance, drawing thousands of pilgrims each year who seek to connect with their deep Christian heritage.
Speaking about the event, Dean Sarah said: “The ties between St Davids and Armagh are more than just historical—they are deeply spiritual. We are reminded that the Christian faith transcends borders, uniting us through shared traditions, values, and a commitment to serving others.”
The service in Armagh marked yet another step in fostering a strong relationship between the two cathedrals, reinforcing the historic and spiritual bonds between Wales and Ireland.
