Have you checked freebmd, using the years of likely births and by just putting in the surname, along with mothers maiden surname, also look at deaths to see if any of the children died.
Unless Ferdinand's lady friends registered the children using his name or took out action to get child support and you can find the legal action with him named then you are unlikely to find them
