Maltese Citizenship by Decent

Good day

My wife's Grand mother and her Grand mothers parents where born in Malta, Does this mean that my wife can apply for citizenship ?
My wife is a South African citizen and my wife's mother is deceased and she was also a South African citizen. Does this now mean that my wife can not get the citizenship as the line has been broken ?

If she can still apply for citizenship what documents will be required ?

An important provision found in the Maltese Citizenship Act holds that if the parent of an applicant was alive on 1st August 2007 and dies after 1st August 2010 without applying for Maltese citizenship, the link is broken and the applicant loses the right to apply.

you should speak to a pro though.
