Oh! OH! Wouldn’t Seamus [usually pronounced SHAY mus] and Aidan be lovely names for twin boys? 

It is said that when King Oswald originally asked the Irish to send a bishop to teach the Faith of Christ to himself and his people, they sent him another man of a more austere disposition.  After some time, meeting with no success in his preaching to the English, who refused to listen to him, he returned home and reported to his superiors that he had been unable to achieve anything by teaching to the nation to whom they had sent him, because they were an ungovernable people of an obstinate and barbarous temperament.

The Irish fathers therefore held a great conference to decide on the wisest course of action; for while they regretted that the preacher whom they had sent had not been acceptable to the English, they still wished to meet their desire for salvation. 

Then Aidan, who was present at the conference, said to the priest whose efforts had been unsuccessful: ‘Brother, it seems to me that you were too severe on your ignorant hearers. You should have followed the practice of the Apostles, and begun by giving them the milk of simpler teaching, and gradually nourished them with the word of God until they were capable of greater perfection and able to follow the loftier precepts of Christ.’

At this the faces and eyes of all who were at the conference were turned towards him; and they paid close attention to all he said, and realized that here was a fit person to be made bishop and sent to instruct the ignorant and unbelieving, since he was particularly endowed with the grace of discretion, the mother of virtues.  They therefore consecrated him bishop, and sent him to preach.  Time was to show that Aidan was remarkable not only for discretion, but for the other virtues as well.  (p.151)
