Recently I was at the Wisconsin Historical Society and went to the 4th floor archive reading room to talk with an Archivist and learned that a resource I can offer clients is direct review of these collections like the Lyman Copeland Draper Manuscript Collection (this provides excellent information about the period in America between 1755 and 1815). Also the archives has an extensive Civil War collection with over 25,000 pages of documents, that includes primary sources including soldiers’ letters, diaries, photos and other materials. So if you have ancestor that was in America at this time, contact me for research service.
