How have you identified this man to be Charles, arr. Sir Allan McNabb, 1853 Tas?
At some time after 1853, Anne BRODLEY has reason to believe that her origins include the  family name FERANDER. I think it is a family name, not a given name.
If her age on shipping record does not match the age you see for the family, 1841 Census, the family in the Census is possibly not your family.
Margaret CARTER and Anne CAVE  would seem to have continued contact over the years, so you might consider that Margaret is the source of FERNANDER information to Anne?
