A small update: I contacted the UC Santa Barbara Library (source of the online Victor catalog) to question the "Georgia Sea Singers" cross-reference for the Minster Singers. They confirm this is a mistranscription and should be "Georgia Glee Singers". Looks like they've made the correction online.

I was wondering if even that was a mixup, but it looks as if the same personnel recorded under different names for different repertoires. (The Georgia Glee singers doing minstrel show songs.) They show up adjacent to one another on a 1901 Gramophone catalog available as a pdf from the British Library, from this page: http://sounds.bl.uk/View.aspx?item=029M-GRAGX1901XXX-0000V0.xml
(You can PM me for a copy of the pdf if you can't get access. I work at a university, so I can get through. There are some lovely and somewhat random photos included.)

More to the point of this thread is that in this full (101 pages, quite diverse) 1901 catalog I can't find any listing of sea shanties titles. There are a few items of a nautical flavor, but not shanties.
