Sisters Kate, 29, and Rebecca Weightman, 39, visited Kiama on Tuesday as part of a two-week holiday in Australia. 

While in Kiama they visited the Pentrich Revolution plaque dedicated to their relative, George Weightman, who died in 1865.

Mr Weightman was among the ringleaders of the ill-fated Pentrich Revolution of 1817, the last revolution in England, which revolted against the British hierarchy after the Napoleonic Wars when recession, poverty, bad government and extravagant monarchy inspired groups of people intent on political reform.

Kiama historian Ray Thorburn told the Kiama Independent in 2014 that, "unfortunately these groups were infiltrated by government spies and history shows that of who were known as the ‘Pentrich Four’, Weightman was the only one to escape execution and he was banished as a convict to Australia".

"It’s 200 years since the revolution this year, so it seemed a fitting celebration to visit it," Rebecca said. 

"We were coming over here anyway, but we found out… We knew George had come over here, but we didn't know all the details. 

"We know that George’s son Joseph went out to Australia when he was 41 but we don’t know if we have any relations in the (Kiama) area."

After doing some research, they learnt that "we're his eighth cousin".

"We searched online and we couldn't believe there was actually a plaque specifically dedicated to George himself," Kate said of the Kiama memorial. 

"We've driven down from Sydney today, (after) we retraced the steps where George Weightman was brought in on the boat… There were 14 convicts that were brought in from Pentrich Revolution," Rebecca said. 

"We saw where the jail was, although it’s not there anymore, and we also went to the quarry where he used to work."

Mr Thorburn said Mr Weightman lived in the Hastings area near Port Macquarie when he first came to Australia. There he met a landowner and moved to the Kiama area, where he worked as a cedar-getter.

“He made a name for himself as a ‘worthy and upstanding citizen’ and resided in a cottage situated near the overhead railway line in Terralong Street where a memorial plaque now sits, and died at the age of 68, having never seen his wife or son again," Mr Thorburn said at the time. 

The sisters also visited the Kiama Family History Centre during their day trip, as well as the Bombo cemetery, where George Weightman is buried in an unmarked grave. 

"We just know he's in the Anglican section," Kate said. 

The siblings said the only person who died in the uprising was shot in their next door neighbour's house. 

"We now still live less than a mile from Pentrich in Derbyshire – our local pub is The Dog Inn which played a role in the story," Rebecca said. 

"The Dog Inn was there during the time of the revolution, but it was called The Spaniel Dog Inn then I believe. There's lots of information in there about the Pentrich Revolution.

"It's our local pub, and it would have been George's local pub. 

"And we have a Pentrich Revolution plaque at the end of our drive because Hunt’s Barn (where) the march started is our neighbour’s house."

Rebecca said members of the Pentrich Revolution Group were planning to travel from England to Australia next October for a series of commemorative walks in Sydney and Kiama. 

She said organisers were seeking descendants of those who took part in the revolution to get involved in the walks. Relatives or any other interested parties can contact reedg@bigpond.net.au.
