We are so lucky to have so many free records online at FamilySearch. The Tax Books for Rutherford Co Tennessee District 10 were my focus yesterday as I collected the information from the entries of my Great Grandfather, William Green Cook--a resident there from 1912 thru 1944. I collected the information and organized it in a Google Sheet which I saved as a PDF along with notes/observations and source information. This process made it easy to upload the PDF to my Family Tree at Ancestry in William Green Cook's gallery. After uploading the PDF, I used the custom event and named one Property Tax for each year. Below is a screenshot of the first sheet of the PDF file to give you an idea of what information I logged.
This information gave me some ideas of other places in which to look for clues about my Great Grandfather.
