The bulk of the A. Walton White Evans Family papers (MC 03) documents the professional life of civil engineer A. Walton White Evans. Correspondence, journals, reports and articles provide documentation of Evans' work as a civil engineer and a consultant on railroad projects from 1838 to 1886.  Family correspondence is dated primarily during the time of Evans' work in Chile and Peru from 1850 to 1860. His letters to his wife Anna are included in a series of her correspondence.The collection also contains a small amount of correspondence between Evans' parents Eliza and Thomas (1800-1815) and between Anna's parents Sarah and John Zimmerman (1841-1850).  Correspondence and records from A. Walton White Evans' grandfather Anthony Walton White and his great-grandfather Anthony White were apparently collected by Walton who had a particular interest in their careers.
