Sorry Millipede your reply must have come in when I was sending the above.
I suspect Hannah was pretty resilient -she survived the death of 3 sons, assault and desertion by one husband and the death of 2 others, but perhaps the court case and possible annulment of her 4th marriage were the last straw.
Her mother died a pauper in 1856 and her eldest brother and his wife were paupers in Costessey in the 1891 census. I presume that was the fate Hannah was trying to avoid.
Maybe she did move away, though I'm not sure where she would have gone and what she would have done, 66 was a bit old to start afresh, even if you do lie about your age! I'll investigate the Hannah Howes in Smallburgh.
