The chief problem encountered is how to manipulate the dating to 1865 for the blog postings.  So far, there is no where than one can modify/customize a date to previous years in WordPress.  This is a primary concern since the postings are to be set in the timeframe.  I’m assuming this may be something that requires customization.   I will have to post a question to a WordPress forum or ask those who have created dated blogs how they did it.
