Hello again
These pages may assist you to follow up on your query.
BUT: It seems there is no on-line index. Separate books are available.
A snail-mail contact with the NSW BDM may be necessary.

The index for the Change of Name register was initially kept in separately bound books from 1875 to 1967. From 1967 to 1996 the deeds were recorded in the Vendors index. Records from 1992 to 1996 must be searched through Deeds Name Search. From 1.4.1996 to date all change of name records have been kept by and must be searched through the NSW Registry of Births Deaths and Marriages. For more information see 'General Register of Deeds'.
A change of name can no longer be registered in the General Register of Deeds. A change of name should be referred to:
