Contents: Invitations, correspondence
Arrangement: The series consists of three small subseries: a sample of general invitations in reverse chronological order, special invitations to the Delmarva Chicken Festival, and miscellaneous accepted invitations.
Description: In the original office files, invitations accepted by Senator Williams were not separated from those he declined. From the original volume of 17.5 linear feet, the sample of invitations retained includes all accepted invitations found within folders selected at five-year intervals beginning with 1948. Folders on special events such as "Dinner with Ike" or the Delmarva Chicken Festival were also retained. Senator Williams rarely accepted invitations to social receptions in Washington, but he generally attended functions sponsored by Delaware fraternal organizations, church groups, or the Republican party.
