There was a James Camaish who married an Esther Gawne in the parish of Jurby on the 17th August 1839. One daughter is showing on IGI as christened on the 27th May 1840 with the name Susannah.

IGI also shows an Anne Isabella Camaish was christened in NSW in 1848 to James Camaish and Esther.

Could your details be slightly wrong or is this coincidence ?
