Likely arrival for the Forbes family from PROV records in Dec 1852 aboard 'Theodore':

Alexander FORBES (48)
Donald (4)
Janet (2)
Mary (1)
Wm (38)
Margaret (29)
Eliza (31)


Not sure which is the partner/chn of Alex and which of Wm, but ages seem to fit...

Marr reg for Donald gives his birthplace as Inverness.
