Can't find/edit widget above header

Our office has recently moved locations and the website admins have edited our address across the website, but we can’t find the widget/module located above the header on our website. (Includes our address as well as FB link and search box.) Code for it doesn’t exist in our theme (that I can see) and it’s not listed as one of the widgets on the homepage. Any insights into where we can find/edit this content?
