the missing Phillips siblings - did they move abroad?

[aniph]

Hi all

I have searched high and low in Irish records and can find nothing so suspect they went to another country!

Walter Phillips baptised Annaghdown, Galway 20 Jan 1845
Thomas Phillips baptised Galway City 29 Dec 1848
Francis Phillips baptised Galway City 14 Jul 1850
there maybe also an Eliza probably born 1830's

Bernard born c 1835 stayed in Galway and Dublin
Michael born 1837 went to New Zealand
and Patt born 1853 stayed in Galway
 I have traced these 3 fairly well.

Any help with the others much appreciated
Oh parents were Thomas Phillips/Ellen Burke/Bourke married Castlegar 3 May 1830
