Albus and she had the plan to have both Ron and Ginny, so that Ron could take over as Baron Weasley and Ginny would become Lady Prewett, because until both of her children became seventeen, all her older children would have become unworthy of the title, because in the family law of the Weasley and Prewett it was stated that the oldest heir had to claim the heirship before his seventeenth birthday or the family magics would have recognized this as abandoning of the potential heir’s duties and the magic would have marked the potential heir as unworthy. This was their plan to wait until all of her older children were of age and were unworthy of the title as heir Weasley or Prewett. But now, their plan had failed and her Ronnie and Ginny wouldn’t receive the titles, they deserved.
