I made transformed some sentences into "not until~" except for number 5. Number 5 was transformed from "Not until~" sentence.
Would you give me grammar check about below sentences?
1.Not until 1865 did when Joseph Lister try the first antiseptic treatment on a compound fracture.
2.Not until the age of 19 couldn't Orrico know the secret of her birth.
3.Not until the age of fourteen could they be found guilty as long as they knew the difference between right and wrong.
4.Not until 2006 when the couple were moving house did they find the bankbook again.
5.Until the bank was clearly given the third degree by Westminister policy didn't go into reverse and a 1.5 point rate cut was ordained.
6.Not until January or February 1996 did significant problems with the accounting system began to manifest themselves.
Thank you bhaisahab. By the way, can I get corrected expressions?
I don't know where I did mistake in the sentences.
NOT A TEACHER
I believe that as long as on sentence 3 should be replaced by considering that.
