Virgin girl does require in her marriage the permission of her father or her paternal grand father. If father and the paternal grand father refuse proposal of marriage with out valid Islamic reason when the proposal is from a Kof’ (Compatible believer) and the girl needs to marry to save herself from sin, then the condition of the father’s permission or paternal grand father’s permission will not remain. That is when the refusal of the father or his father is not based on a valid Islamic rules.

Quran says: Ask those who have the knowledge if you don't know. فاسألوا أهل الذكر إن كنتم لا تعلمون Sura Al-Anbiyaa, verse 7. Obviously we can not ask a dead scholar no matter how high was his knowledge.

Mujtahid must be alive to understand the exact situation of any matter then deduct the Islamic rule of it from Quran, Sunnah, Aql and Ijmaa'.

Sunni Muslims follow dead Shaikhs like Abu Hanifa, Shafi'ee, Malik and Ibn Hanbal. Even Salafi or Wahabi sects follow Ibn Taymiyyah. All of them died before many centuries and never witnessed nor knew about our current issues. Following dead scholar does not fulfill the need of guidance at all because full guidance needs full knowledge about the situation which is with a living eligible scholar not with a dead scholar.

All Hadeeths asking us to refer to the scholars never asked to refer to dead scholars but living scholars who can be asked and who can reply after understanding the situation.

The most learned Mujahid among Shia Ulama can be known through valid witnesses of at least two of the high caliber Ulama in the Hawza who are called Ahl al-Khibra or Khubra أهل الخبرة.

It is not for any one else out of the high caliber Ulama to give witness in this matter. 
Hawza Ulama usually guide people when the need arises.

There are few high learned Mujtahids but you need two high caliber Ulama to give you their wtnisses.

Wassalam.

You need to follow the witness of two of more of Ahlul Khubra أهل الخبرة 

Ahlul Khubra are the high standard of Ulama in the Hawza who know the level of knowledge of the Mujtahids and define who is the most knowledgeable among them.

The linguistic meaning of it is (Peace be upon him) which is in fact used for every Muslim when you say to him : Salamun Alaykum.(Peace be upon you).

But as a term and common understanding , we have to be careful in using it to avoid mixing between the Infallible and others.

You need to start very early in teaching him the basic Islamic knowledge, in a way which makes him like this knowledge and continue gaining it in the Hawza ( Islamic seminary).

Becoming a high level Mujahid needs decades of continuous hard work in seeking Islamic knowledge along with sincerity and humbleness which are essential in enlightening the heart.

Wassalam.
