We have a notebook at the archive, listing all the sources we have available at this time. We also have several "working files and spreadsheets" that can be accessed from our computer for researchers. We have ALL naturalization records; ALL Common Pleas Journals and ALL early probate packets from the Probate office. You must have a NUMBER for the probate packet - not a surname, which can be obtained by traveling to the Jefferson County courthouse and searching for your surname in the indexes. Once the surname(s) is located, you can locate the "case file number" which is needed to located the packets at our archive.
