Joseph Rass Gore is buried in the Champion Cemetery you list and is the Joseph Gore in the death record you give. Which leads me to another question.
Who is George W Gore, born abt 1884 in the 1920 census? Also can't find Sarah Mintz.
Possible match in the 1920 census for Brunswick Co, NC: GORE, George W. age 36 b. NC, both parents b. NC wife Sarah A. age 47 b. NC, both parents b. NC dau Ida F. age 16 b. NC son Joseph R. age 13 b. NC son John M. age 10 b. NC
