I'm looking for date of death and burial place for: Mattie R. Dorsey who m. David H. Duncan. They were in Louisiana in 1900, but are found in Ward 3, Pine Bluff in 1910 & 1920 and Mattie is widowed. Her mother, Virginia Elizabeth Graves Dorsey is living with Mattie in 1910 & 1920 (age 75). Would appreciate any help in finding when and where Mattie and Virginia were buried.
