On the trail of Cobb and Co's founders

This year marks the 150th anniversary of the beginning of Cobb & Co and Ms Nicholls hopes to spend a good part of the year wandering through cemeteries.

"We're researching a number of the Cobb & Co graves," she said. "There is a social history with graves and this year is a good opportunity to explore that."

She said there was one grave in particular which she was trying to find.

"Lewis Rogers was one of the original Cobb & Co drivers. He died of pneumonia in 1867," she said.

"His family contacted us last year, so we're trying to track down his unmarked grave."

Mr Rogers is believed to be buried in the Presbyterian section of Orange Cemetery.

Ms Nicholls said a number of people associated with Cobb & Co were buried in Orange.

"Cobb & Co started when a group of Americans came to Melbourne to set up a transport company. The company then relocated to the Central West of NSW with a number of directors and workers ending up in Orange.

"As we go along we learn more and the pieces come together to make a picture."

One grave site which is prominent at Orange Cemetery is the family plot of Cobb & Co director, WF Whitney.

Whitney is buried in the same plot as his wife, his two infant children, an adult daughter and son-in-law.

Ms Nicholls said she was also on a quest this year to find where Cobb & Co directors from outside Orange were buried, in locations in Goulburn and Melbourne.

"We'll link it all up as a research project," she said.
