Grandfather: Jerry BOSTON (Source: Liberty Center Methodist Church, written by Mrs. Orville THOMPSON, copied from the History of Warren County, Iowa, by Gerard SCHULTZ and Don L. BERRY, The Record and Tribune Company, Indianola, Iowa, 1953, pages 119-151.)
John THOMPSON and his family were original members of the Orilla (Pleasant Ridge) Methodist Episcopal Church. (Source: History of Orilla Methodist Church is copied from the History of Warren County, Iowa from Its Earliest Settlement to 1908 p.333)
NOTE: At this time it is unclear whether the J. THOMPSON whose grandfather was Jerry BOSTON and the J. THOMPSON whose family were original members of the Orilla Church are the same person.
