I show James Disney age 70 living next door to Achsa Martin on the 1850 census. Achsa had a brother Grove Disney who was born 1832, probably in Baltimore Maryland and died 1905 in Garrison, Nebraska
James Disney was Achsa's father. He was born in Maryland. James had brothers Richard, William I.(ca 1778-March 1842) Mordecai and a sister Elizabeth who wed Moses Deaver in 1794. (I'm part of Elizabeth's line.) Their parents were James Disney (1755-1827) and Rachet Pickett. I have more info if you need it.
Do you have all of the children of James Disney and Elizabeth Leasure?
