James Rigby arrived in Van Diemen's Land in 1834 to serve seven years hard labour for highway robbery, before spending the next 55 years in Nile.
As many as nine generations later, about 100 of Rigby's descendants will gather at the Evandale Football Club for a mass family reunion.
Evandale’s Michael Rigby encouraged his extended family members to bring along any memorabilia they may have to the November 26 event, which will run all day from 10am.
“There's so many Rigbys out there, I've got no idea how many of us there are,” Mr Rigby said.
“We're a strong and proud family and I think we're known for sticking up for each other, and it'd just be great to get to know everyone.”
Anyone who has information on the Rigby name or who would like to attend the event is encouraged to contact Reg on 0400974611, Sheila on 0408132556 or Rachel on 0427029788.
