Jimmy was an exceptionally careful correspondent, typing all of his letters and keeping a carbon copy of each. The letters referenced below are largely due to his life-time care in maintaining files of all his correspondence.
The sequence of Tedi and Jimmy's moves around the country is roughly as follows -- Los Angeles after their marriage in 1936 to 1948, Santa Fe from 1948 to 1950, Lubbock from 1950 to 1951, Marietta from 1951 to 1954 and Atlanta from 1954 on. Jimmy spent a portion of the years 1942 and 1943 working as a surveyor on the Pan American Highway in Costa Rica, Nicaragua, Guatemala, and Panama as an employee of the Army Corps of Engineers.
