Bessie at Ancestral Ties broke the news a few days back (but it took me until today to see it since my RSS feed in Apple Mail tends to be temperamental!) that the John Morgan collection has been digitized by the University of Utah Marriot Library. This is exciting for anyone working on the history of the Morgan family or the Southern States Mission.
See Bessie's post at Ancestral Ties (John Hamilton Morgan Collection available at the Mountain West Digital Library MWDL) and the collection, viewable at the Mountain West Digital Library. (Collection: John Hamilton Morgan Papers.)
As an example of the holdings in the collection, here are the first and last pages of a letter written by John Morgan to Matthias F. Cowley in 1879. What a treasure to have this collection available online!
