Thanks again....  I'm learning so much through these brief encounters.  Much appreciated.

Yes…I’ve learned a great deal by being on Rootschat.

Oh really interesting - thank you.   I'm clearly not much chop at Ancestry searches! Is the workhouse info in the card catalogue or just a general search ?   I did discover that when Mary Ann married, she said her father Francis was a lawyer - not too far from the truth as he had worked in various solicitors' offices in Hobart too.
Also interesting that Isabella says her father is a schoolmaster.  When her brother George informed the Hobart authorities of his father's death, his (George's) profession was schoolmaster.

I searched the 1841 census specifically (by getting it out of the card catalogue first) I find it often produces a better result doing that.  They are both spelled WHETTON ages 13 & 10
