No that was not the right one, as the IGI gives an Ann Gelling born Castletown but with a different father.
The IGI lists Ann Gelling , daughter of Edward Gelling and Isabella Quayle, Christened 7 Nov 1841.
There is an Ann Gelling , Marown, married Henry Quilliam 14 Jul 1863 in the IGI.
She appears in later census details, but the children's names I saw briefly didn't reflect the family you gave.
Hope this is some help.
