Nelson Hall, age 52, married Alice Ingram, age 26, on 1 Apr 1897 in Jefferson Co, MS
Land records for Jefferson Co, MS are available on familysearch.org. To find them go to the site (you will need to sign up for a username & password, but the site is free) and under the search button go to catalog. Enter the place as Jefferson Mississippi (do not use the word county). Then go to land records. Search the indexes first for his name and note the book and page number. Return to the list of land records to find the book. I was quickly able to find two entries for his name and I assume there are others.
