Hi Tracey,
With reference to the tree you mentioned on Ancestry which notes that Charles Edward THOMAS died in Victoria, the year they give is 1925 at Box Hill. There is a death registered:
Chas THOMAS
Death Place: Box Hill, Victoria
Age: 98
Reg Year: 1925
Reg Number: 8301
I assume that they have a copy of this certificate, but you should contact them or purchase a copy yourself to confirm, and it should tell you whether or not he was born in Tasmania. They also have details of Charles' origins, so again you should contact them to share information.
They also claim that it is the same Charles who had a relationship and several children with Emma LUCAS from 1882. Assuming that Mary Ann died somewhere between 1875 (the birth of her last child) and 1882, I can really only see one possible:
Name: Mary Thomas
Death Date: 12 Aug 1881
Reg Place: Hobart, Tasmania
Age: 60
Reg Number: 3315
After 1882:Name: Mary Ann Thomas
Death Date: 3 Apr 1885
Reg Place: Hobart, Tasmania
Age: 42
Reg Number: 2329
Name: Mary Thomas
Death Date: 1 Dec 1892
Reg Place: Beaconsfield, Tasmania
Age: 70
Reg Number: 32
You may find it difficult to trace Mary Ann's origins without supporting documentation. Stating that she was a minor when she married simply meant that she was under 21 years of age. She may have been born in Tas or she could have come from elsewhere, whether it was from the mainland or from overseas. The Tas immigration records are quite poor, and not all have survived. The Archives web site is in the process of transcribing them so continue to check back. You can also check the newsapapers, as sometimes incoming passengers were named. It might also help to check out other UNDERWOOD families who may have been around Launceston at the time they were married.
