My Grandfather, Robert B Mhoon Sr., was the Assessor for Richland Parish around 1901. In 1905 he was reappointed by Gov Blanchard.
I've the New Orleans Daily Picayune from Oct 6, 1907 with his obit which mentions: ...The assessment in acreage, description and valuation is absolutely correct. He not only checks over the land every year, but since he has been in office has made two maps with the name of each landowner inscribed on his land and brought the changes of title down to date. The latest map is of incalculable benefit to the public as well as this obliging officer who has distinguished himself as the only assessor who ever took this much pride and interest in his work in this parish...
Thought I'd pass this on for any of you who may be close enough to Rayville to inquire about those maps for genealogy reference purposes.
