Context paragraphs:
Thomas C. Mann: Thomas Clifton Mann (November 11, 1912 – January 23, 1999) was an American diplomat who specialized in Latin American affairs.  He entered the U.S. Department of State in 1942 and quickly rose through the ranks to become an influential establishment figure.  He worked to influence the internal affairs of numerous Latin American nations, typically focusing on economic and political influence rather than direct military intervention.  After Lyndon B. Johnson became President in 1963, Mann received a double appointment and was recognized as the U.S. authority on Latin America.  In March 1964, Mann outlined a policy of supporting regime change and promoting the economic interests of U.S. businesses.  This policy, which moved away from the political centrism of Kennedy's Alliance for Progress, has been called the Mann Doctrine.  Mann left the State Department in 1966 and became a spokesperson for the Automobile Manufacturer's Association.

Charles H. Thomas (sports executive): Charles Herbert Thomas (born November 22, 1876 Gardner, Massachusetts – died August 19, 1968 in Biscayne Park, Florida) was the president of the Chicago Cubs of the National League from 1914 through 1916 .  A stenographer, Thomas joined the New York Giants as assistant secretary in 1900.  After Giants press agent Charles Murphy purchased the Cubs from Jim Hart in 1905, Thomas followed Murphy to Chicago and became Secretary of the Cubs.  Thomas briefly resigned his position in 1909, after a storm of bad publicity connected to his divorce.  It seems that Mrs. Thomas discovered her husband cavorting with another woman, a Mrs. Helen Loker, and alleged Thomas threatened to kill her if she went public with this fact.  The divorce came through, and Thomas eventually married Mrs. Loker.  In 1914 Murphy appointed Thomas the club treasurer.

He was lord of the manor of Garway at Garway House in Herefordshire.  The Irish peer married Jane, daughter of John Berkeley of Spetchley by Jane Compton.  They became Roman Catholic and joint owners on their marriage of the several properties including Longmores, Lodge Farm, Church Farm and Coleman's Farm; and later New House Farm, Cwm Madoc Farm, Garway Court, Great Demesne Farm, and the Darren Mill on the River Monnow.  The whole estate comprised almost 3,000 acres.  The lordship included riparian rights to take profits from the river; with excellent salmon fishing in Victorian times, it was a lucrative tenure holding.  In 1808 it was held jointly between Southwell and Robert Cannings Esq, who were also entitled to sit at the Court Baron, appoint the steward, and pass sentence on legal cases such as encroachment, amercements, obstruction and presentment; and the appointment of a petty constable to the parish.  Lord Southwell appointed Thomas Wakerman of Graig, another Roman Catholic, in 1810 to be his manor steward.  Wakerman was also a solicitor and eminent local historian.  Lord Southwell only visited the county on a few occasions, to shoot pheasants.  The rest of the time he spent in Ireland, London and the south of France.  They had two sons and three daughters:
