Ann Middlebrook was sentenced to 14 years for stealing in Stafford, England and was sent to Australia but that was just the beginning of her story.
She was one of 401 convicts transported from England on the Glatton to Australia in September 1802.
She first landed in New South Wales in 1803 before she married army sergeant named James Keating in 1804.
Mr Keating was reassigned to Port Dalrymple and as they arrived Mrs Middlebrook gave birth.
He was to be the first child of British descent born in Northern Tasmania, William Dalrymple Keating, in what is now known as George Town.
However, the marriage was short-lived as in 1806 Mr Keating and three other men were convicted of stealing from a government store at the Port and were sent to Sydney for a trial.
He was found guilty and returned to Hobart where he was hung for his crime in April. His son William was only two years old at the time.
Thankfully the couple had befriended the Reverend Robert Knopwood and he spent most of the day before Mr Keating's execution with him and accompanied him to the scaffold.
Mrs Middlebrook remarried Joseph Edmonds in 1811 and lived the remainder of her life in Longford until her death at 86 years old in 1841.
A replacement tombstone marking her grave was unveiled and blessed on Saturday at Longford's Christ Church at 1.30pm.
Len Langan gave an introduction on Mrs Middlebrook before Reverend Edrick Corban Banks blessed the new headstone.
"Ann Edmunds (Middlebrook) is a significant character in Tasmanian history and deserves this recognition," Mr Langan said.
"Having spent most of her life at Longford she became a well-liked and highly respected person known to the locals as nanny Edmunds and befriend of the then Rector R.R.Davies who conducted her funeral service.
"Her memorial stone was last replaced in 1941, this replacement is due to the Mrs Claire Jones of Longford."
Alison Andrews unveiled the replacement tombstone in lieu of Northern Midlands Council's mayor Mary Knowles who was absent due to illness.
