I may be able to clear up some things for you. Elizabeth Disney who wed Moses Deaver was the daughter of James Disney and Rachel Pickett. In an Anne Arundel County deed (WSG No. 141828-1829pg 527-529) it names the heirs of James Disney as sons Richard, Mordecai, and William and the heirs of (his daughter) Elizabeth Deaver who were: Elizabeth Deaver, James Deaver, Charity Reynolds, William Deaver and Rachel Disney. This Rachel Disney was the wife of Thomas Spurrier Disney.
There aren't any Benjamin or Snowden Disneys in this line.
