Mandy and I searched for a long time online for evidence of Dorrie's birth as we suspected she may have been the child of one of James Ralph Matthews daughters or possibly the sons.
Sorry, there is just one more piece of information for Dorothy Ellen Matthews birth that was included with that.....
'At Mrs TREWEEKS, Mount Street, Burnie.
Interestingly, at that same address, I found a birth record for another child who died very young...(about 5 months)
MATTHEWS Basil Ken
Birth 19 Mar 1915
At Mrs Treweeks, Mount St. Burnie
Reg. Year 1915
Reg No.1960
James Ralph Matthews
Lillian Matthews nee.Tiffen
The information I've given was what I found from the Hobart Library resource online inside the library building. They provide access to the Pioneer and Federation Indexes and it's limited to searching on their own computers in the library itself.
There is access to the Names Index through the family history portal through Tas Libraries online remotely. But nothing could be found on there, but it is a very handy resource.
(For reference if anyone is interested;)
