Did William Wallace really have an Irish recruit by the name of Stephen?

Answer 1

No, there was never any known contact that William Wallace had with any Irish recruit, that story is taken from the film Braveheart, which is saturated with historical inaccuracies, despite being a great film, it should be accepted on the understanding that what you see in it is mostly complete nonsense in terms of historical accuracy.

In truth, the Irish, whom were known as the 'Hiberni' at this time, were actually enemies of the Scots, a lesser enemy than the English, but just as much an enemy none the less, the Irish often sided with the English and sometimes did double deals with the Scots and English;

One example in particular is that when the brother of King Robert I of Scots, Edward Bruce, was offered the position of being King of Ireland if the Scots drove the English out from the Southeast of Ireland, at the loss of the battle of Faughart, an Irish peer Sir John De Bermingham, had the dead body of Edward Bruce quartered and his head salted, then sent to Edward II of England to be put on display, while the rest of Edward Bruce's body was sent to various towns around Ireland.
