Name	Lifeboat from Titanic	Lifeboat to Carpathia	Confidence Level
Calderhead, Mr Edward Pennington	5	7	4.00
Flynn, Mr John Irwin	5	7	4.00

A 1938 interview with Flynn says he and Calderhead entered the same boat.

Gracie's book The Truth About the Titanic, page 228, says Calderhead, Flynn, Ruth and Washington Dodge Jr all transferred from #5 to #7, but gives no confirming information.

According to Pitman at the American Inquiry, page 299, "My idea of lashing Nos. 5 and 7 together was to keep together so that if anything hove in sight before daylight we could steady ourselves and cause a far bigger show than one boat only... I transferred two men and a woman and a child from my boat (#5) into that boat (#7.)"

We are reasonably sure, but not positive, that Calderhead and Flynn were two of those who transferred #5 to #7.
