You have compiled a great amount of information!
When I was checking the BDM of VIC I assumed his birth record was a different one. There seems to be records of 3 people being born on the Phoenix in 1854. Would this be a different ship?
The three records are -
Unnamed PHILIPS, Male, Ship Phoenix, Father - Thomas PHILIPS, Mother - Margaret (Unknown), Birth - At Sea.
Unnamed DONALDSON, Male, Father - Thomas DONALDSON, Mother - Margaret (Unknown)
Agnes Phoenix EVANS, Female, Father - Thomas EVANS, Mother - Sarah (Britin)
I don't know if this helps or hinders?
