Bizarre goings-on include mysterious writings and ancient Welsh script appearing on the bare stone walls, a tombstone in the garden is supposedly able to move unaided, icy chills can instantly send the lounge temperature to -15.

Then there's the muffle of voices from unseen people, footsteps on the stairs in the small hours, faces at the windows and an unknown force "sitting" on the edge of the family's beds. And that's on top of the ghosts of a young girl called Jane, a boy named Tom, a creepy cat as well as the former haunting said to have been carried out by a 16th century monk the family dubbed Brother Doli.

But the family - Rose-Mary, husband David and son John Paul, 17, (the Gowers' grown up daughters have since left home) - seem to take the events in their stride after six years. In fact, Rose-Mary and David even accuse each other of causing the phenomena as they too are at a loss to find logical explanations.

Paranormal experts from Liverpool's John Moore University have conducted a lengthy investigation at the family home at Treuddyn, near Mold, and are due to publish their findings later this year.

The spooky saga started a few weeks after the family moved to their rambling house nestled in a valley when a reporter from the local newspaper was knocking on the doors of the few houses dotted about the valley try to find the owner of a nearby field.

Rose Mary pointed out that she had acquired the field and the reporter told her that the newspaper had received a call from an Irish couple who had been walking through the area when, they claimed, the Virgin Mary appeared to them, an event which had cured them of their minor aliments.

The story was picked up soon after by a national newspaper in February 1997 and then pilgrims began travelling to the field.

Rose Mary said: "Some people claimed cures others just stood at the gate and took in the vibes. Some people said standing there had cured their frozen shoulder so I tried and after a few minutes it began to clear up. The next day it was gone. I'm not claiming it was a miracle but it is interesting."

The next stage of the encounters happened when one of the Gowers' daughters saw a monk and Rose-Mary went on to see him a few days later, believing him to be another pilgrim who had come to visit the "miracle field". Little was she to know then that that the ghost of Brother Doli was to become a familiar character around the family home. He became known as the graffiti ghost due to the ancient Welsh daubings and symbols which materialised on walls around the home.

Brother Doli was first seen in January 1999 and last seen in March 2001 on the 16th birthday of John-Paul, who has Downs Syndrome, and who came to see much of the monk.

Two weeks later Rose-Mary was expecting the visit of a woman from the Environment Agency as part of some work being done on the family home.

Rose-Mary glanced out of the window on the morning of the visit and saw a woman stroking a cat on her patio.

Looking closer she exchanged glances with the woman and noticed that she seemed extremely young, more like 12 than in her 20s. But when Rose-Mary went outside to greet her visitor - she says she found no-one.

"She looked like a flesh and blood person," said Rose-Mary.

If that were not strange enough then the name Jane began appearing on walls in the house and inscribed in a tree - although it looked like it had been there for some time - and the face of a woman seemed to materialise on the fireplace in the lounge.

It should be pointed out that in the grounds of the house is a tomb stone carrying the inscription Jane Jones, aged 15 1778. It was once moved by the family but was found back in position the next morning. It can now be found leaning up against the lounge wall after falling over three times after it was moved on a second occasion.

Meanwhile, as well as Rose-Mary's supposed "ghost cat" which has a tendency to sit on the couple's bed - while they're in it! - there have also been instances when the temperature of the lounge plummets. It's been recorded at -15 at the same time it took three minutes for a separate thermometer to register whilst it was IN the freezer.

"It's not gradual and it's not a draught," said Rose-Mary. "There is a sudden icy chill and you can feel it swirling around the room."

But there was still more to come. Rose-Mary was taking photographs about her home, including the barn in the field of the supposed Virgin Mary sighting.

Friends were thumbing through them when one noticed a strange image in the window. When the image was magnified it shows the face of a man. His collar can be seen along with his shoulder-length hair.

Rose-Mary now believes this to be the face of Tom, a boy who has been seen in the window of the bedroom of her home and in the garden.
He appeared in March 2002 when John Paul complained that a boy was in the study reading one of his favourite James Bond books.
On another occasion John Paul was helping his mother with some gardening work when she sent him off to the compost heap with some weeds.

Looking up, she says she watched "him" disappear out of view. "I thought 'where had his baseball cap gone' and also that his hair seemed really long, especially as John Paul's is so short." Rose-Mary went on to say that she then saw John Paul come into view from totally the opposite direction.

Like the name Jane, Tom also started to appear on the walls of the family home.

In August 2002 the Gowers began to find snails climbing the walls of the lounge of the house, and with them came the so-called silvery "snail trails". Rose-Mary took this photograph which she says shows a "snail trail" spelling out the word Jane.
