Hello majm and MERLIN
I am still trying to resolve why certain records for the family of Henry Davis sometimes indicate that he was instead Henry Morgan.
A son Thomas was registered as Thomas Morgan at birth 1858 #11925 Indented Head but died as Thomas Davis Oct 1904 Eaglehawk#11253.
Baptism records from St Mary of the Angels Geelong for a number of siblings alternate the surname Davis and Morgan.
So far as I know the large family was always known as Davis.
Catherine Monaghan (with variations) is consistantly recorded as the mother.
Henry and Catherine are supposed to have married C1842 Portland Bay (recorded on children's birth records).
