Re: Losses of Seamen
Although this book does not have that many names it does have a short chapter on Peterhead Whalers that describes life at sea and how the town of Peterhead coped with men at sea.
The book is "The Great Days of Sail Reminiscences of a Tea-Clipper Captain" by Andrew Shewan. Andrew was himself a sailor, the captain referred to in the title.
Regarding selecting a time frame for your study, this book says:
"Though Aberdeen had declined, in 1860 Peterhead was at its height as a whaling port. In that year thirty-two vessels left for Greenland, all sailing-ships, and the largest number, I believe, that ever left on one occasion. Thereafter they quickly diminished, until by the seventies there were only two or three left." (p. 102)
