I Have read two interesting Pieces concerning McGough.
1. His Affidavit from The Senate Investigation
Electronic - Fully Searchable - transcripts of the complete U.S. Senate and British Board of Trade inquiries, and reports, into the sinking of the S.S. 'Titanic.'
www.titanicinquiry.org
2.His Letter to his Mother Which can be found in:
Our Nation's Archive : The History of the United States in Documents
by Jay Crosby (Editor), Erik Bruun (Editor)
There are some differences between the two.
two differences off the top of my head are:
1. In his letter to his mother he claims he got in a lifeboat to persuade the female Passangers to get in.
in His Affidavit he claims he an officer got hold of his shoulder and told him to get in.
2. In the letter to his Mother he claims 55 Passangers in his Boat.
In the Affidavit the Number is 28.
I also got some interesting info from:
Molony, Senan. The Irish Aboard Titanic
and from some Research at Philadelphia Central Library
