Thomas is buried in an unmarked grave in Echua, Victoria, Australia, therefore there in no headstone. The information on his death certificate was given by his second wife of only five years and is very limited.
There is no information given on his first marriage certificate as it comes from church records in 1851 and only records names of bride and groom.
Thomas did not have children by his first marriage and the information for his children of his second marriage is given by his wife.
Thomas' son, Herbert was born in 1882 and Thomas' age is given as 56 years. This would make Thomas' birth year 1826.
His death certificate of 10 March 1885 gives his age as 58 years.This gives his birth year 1827.
The information on records that I feel is given by Thomas himself is as follows and I believe would be the most accurate, but is not substantial.
Second Marriage Certificate
Date: 3 January 1879
Wife: Lydia Miles/Sharp
Thomas' birthplace: New York, USA
Age at Marriage: 53 years
Father's name and occupation: Thomas Warren, mariner
Mother's name: Maria
This makes Thomas' birth year 1826.
Melbourne Gaol Records state:
Age in 1860: 35 years
Native Place: New York, USA
Arrived in Australia: 1851 per 'The Jessie'
This records makes Thomas' birth date 1826.
It is very limited information, but all I have been able to uncover in Australia.
Thanks for assistance.
