Today a new Missionary Database from the Church History Library will be announced during Rootstech in Salt Lake City. This new database contains information about all the early missionaries sent out to the world from 1830 to 1930.
You can search the new database on the Church History Library’s website.
Of course our favorite early missionary Alfred Cordon is in the Database and if full of useful information as well as links to original documents. Take a look! https://history.lds.org/missionary/individual/alfred-cordon-1817
