On March 10, 2009, John Carver executed his will, which was witnessed by William Hobson and Sam Witt. By his will, Carver devised his farm, Stonecrest, to his nephew, Roy White. The residue of his estate was given to his sister, Florence Carver. A codicil to his will executed April 15, 2009, provided that $50,000 be given to Carver's niece, Mary Jordan, and $50,000 to Wanda White, Roy White's wife.
The codicil was witnessed by Roy White and Harold Brown. John Carver died September 1, 2009, and the will and codicil were admitted to probate. How should Carver's estate be distributed?
