Hi All
Not good news on all fronts. Someone very kindly did a look up for me of the St Matthews RC records in the Hawkesbury City Council Library, and there was no further information on the Register than was on the Marriage Certificate for Edward Cullen and Jane Harrison.
I also heard from NSW State Library today, and they have searched all records that they hold for Edward Cullen's baptismal record and were not able to find anything. What they have is the same as SAGS and included some records from the Mitchell Library.
The State Library person did say that St Mary's Cathedral still holds some records that have not released.
So I am very disappointed, but will keep hoping. I will also put a post on my other thread.

Annette
