Hi Julie
Yes, the 1893 marriage record is disappointing.

* Are you aware of your Maurice McGRATH having had another marriage (i.e. after the death of Sarah Jane in 1930) ?? [Yes I realise that Maurice's death certificate notes only one wife, Sarah Jane nee OAKMAN. ]
The reason I ask is because of the following >
TROVE - "The Cumberland Argus & Fruitgrowers Advocate" (NSW) - 26 November 1941 - page 12
Mrs Frances McGRATH (66) wife of Mr Maurice McGRATH of Blacktown, died last week at Parramatta District Hospital ... [
