Ann Lutman is listed in your data base as arriving in Australia on the Persian in 1827. I think that was her departure date, I think it was 10th April 1827. I have no problem with this which is what I think did happen.
If I search your data base further using Ann Lutman’s maiden name of Ann Williams I find she sailed on the Sovereign ship July 12 1827 and again as Ann Williams on the Louisa ship she August 21 1827.
Are these 3 entries in fact all about the same person.
Among my records I have 2 different convict numbers 47935 also 43766.
I carn’t remember where or how I now have TWO numbers for her. Do your records include Convicts number which might help my search?
Yours, Laurie Hudgson
