Thanks for the replies. Since I posted my original message I have been able to update my records on Patrick & Ann. Ann snr. death record lists her father as Tom Murphy yet on Ann & Isaac's marriage record he is listed as Walter Mullally.
Their first born Joannes, born Sept.1833, Gosport RC,Hampshire England, died October 1834 in England.
Their daughters Margaret, 1836 Dublin Ireland,died 1899 in Australia,
Ann, born 1839, Mauritius,died 1877 in Auckland,New Zealand
Catherine (Kate) born 1843, West Indies, died September 1880, in Auckland,New Zealand.
No information yet on what happened to Patrick Timmins, although since wife Ann married Isaac Taylor in 1848 he obviously had died, but where & when.?
