Where Can I Find Info on an African American Ancester That Died Between 1900 1910

I am trying to find death and burial information on my g-grandfather SAMUEL WILSON b. 1847 +/= 2; In 1900, he and my g-grandmother ROSE WILSON lived in COKESBURY w/3 sons, Sherman, Alexander & Julius. However, in 1910 my g-grandmother is listed as a WIDOW and is now living in HODGES with her son Julius's family. So, he must have died between 1900 & 1910.
