The Connecticut State Library has just added the lawsuit that Cesar Peters filed against John and Nathaniel Mann in 1789 and 1790.  You can view the originals at http://cslib.cdmhost.com/cdm4/browse.php?CISOROOT=%2Fp128501coll7, but they are issued page at a time.  We've put the two lawsuits in Adobe Acrobat files for easier viewing, and are currently working on transcriptions.
