A book of maps "Family Maps of Bienville Parish, Louisiana" shows the original land patents. I looked at the entries for Brice--several names with parcels 1837 to 1853. Several Pauls (last name Paul) with parcels 1882 to 1906. McDowells--4 names, two are 1856 and 1860, but the ones you are probably most interested in are Millard McDowell, a land patent of 40 acres in Sect. 4, T15N R8W in 1908, and Walter McDowell, 40 acres in Sect. 2, T17N R8W in 1919. The latter was just over the line in Webster Parish.
