Hi Wallytat,
Clifford Harwood Hayes the son of my Great Uncle Alfred Hayes, married Elva Josephine Mckinley 1937. Elva is a Granddaughter of Hugh Mckinley.
I have found little on Hugh Mckinley. He was assigned to R C Dillon in the Paterson NSW area according to the 1837 General Return of Convicts.
He died aged 36, 14th Jan 1851, Irish Town, NSW (Cumberland Area).
I will be in contact with you shortly as further Info On Hugh is at another location.
Regards,
John.
