Bahrain's UK expat community is "in shock" but "rallying around" to help Britons who have lost loved ones and relatives in the Gulf boat tragedy.
Rev Alan Hayday, Dean of St Christopher's Cathedral, also said he knew of at least two British children who had been orphaned by the disaster.
Twelve Britons and three people with UK dual nationality were among 57 killed when a boat capsized off Bahrain.
The British Embassy is providing counselling to the bereaved.
Rev Hayday said: "It's all come as a bit of a shock but, in good expat tradition, the community is rallying around and preparing to meet any needs they can from their resources, certainly caring for those who have been bereaved."
There were at least two children who had been orphaned, he said.
"There may well be others too because I know there were couples, husbands and wives on the boat."
Robin Lamb, Britain's Ambassador to Bahrain, said next-of-kin of all the British victims had been informed.
"While the Bahraini authorities continue with their investigation, our focus here at the embassy continues to be to support the bereaved," he told BBC News.
A specialist rapid deployment team, consisting of seven Foreign Office (FO) staff and two Red Cross officers, had arrived from London was now helping British survivors and the bereaved, Mr Lamb added.
An FO spokesman said the names of the dead were not yet being released, at the request of their next-of-kin.
The boat capsized at about 2145 local time (1845 GMT) on Thursday, near one of the bridges linking the capital Manama with al-Muharraq island, Mr al-Ghatim said.
Rescue boats and helicopters were quickly despatched and survivors and victims were pulled from the water throughout the night.

At least 67 people were rescued from the al-Dana vessel, while two are still missing.
The search mission is continuing in close co-operation with the US navy.
Police are questioning the captain of the boat after local prosecutors in Bahrain said he was not properly qualified.
The boat's owners blamed overcrowding for the disaster, pinning blame on the tour company operating the vessel.
Correspondents and eyewitnesses have reported that the boat appeared heavily overcrowded before it set off into the harbour.
Officials earlier said that they believed there were 137 on board when the incident occurred, but the figure was then revised to 126.
Bahraini officials say it is too early to say what caused the boat to overturn, killing mainly foreigners.
Most of the passengers were foreigners from construction firms, celebrating the completion of part of the Bahrain World Trade Centre towers.
Murray and Roberts, the construction company which organised a party taking place on the boat, said three British employees and one of dual South African/British nationality had been confirmed dead as well as a further seven staff.
Its remaining 15 employees on the boat, including eight Britons, had all been confirmed as safe, chief executive Brian Bruce said.
UK-based construction company Atkins has said five members of its Bahrain-based staff, as well as three partners or relations, have been confirmed dead.
Keith Clarke, the company's chief executive, added that one staff member and one relative were also still missing.
Bahraini officials have said those who died were of 16 nationalities, including Egyptians, Filipinos and South Africans.
