In the address which was read to her when she laid the foundation stone, some of her good deeds were enumerated: 
The poorer inhabitants, the labourers and mechanics especially, will gratefully acknowledge that to your unexampled liberality they are indebted for many of their past comforts, for their present employment and for the education of their children.
Mr George Rohrs, secretary to the Clock Tower trustees, 3 October 1836
 On the opening day of the Clock Tower, 2 October 1837, there was a festival, followed by annual commemoration festivals which may also have been funded by Mrs Thwaytes.
There is a blue plaque, recording that she funded the Clock Tower, at Central Parade, Herne Bay.

According to the late Herne Bay historian, Harold Gough, Mrs Thwaytes suddenly "took a huff" and left Herne Bay.
After the Clock Tower had been opened, builder George Burge began work on the old St John's Church in Brunswick Square.
Eventually the money ran out; Burge ran out of bricks and had to delay completion.
Around 1839 to 1840, Burge informed Mrs Thwaytes that if the Clock Tower's bricks had been available for the building of the church, St John's would have been completed "long before."
In response, Mrs Thwaytes left Herne Bay, never to return.
