Hi Mary Sue, I have searched all the books that I have on Bienville Parish and have not located anything on your Henry Diamond, or Mary Ann, sorry. If you and others would like to research land records in Lousiana and some other states, please visit the following: http://www.glorecords.blm.gov This is the Bureau of Land Management site and has over 2 million Federal land title records for the following states: AL, AR, FL, IL, IN, LA, MI, MN, MS, MO, OH, & WI. Good luck on your research, Peggy
