Harvard University. Board of Overseers. Committee Assignments pamphlets, 1941, 1947-1961

This subseries pertains to McIlhenny's association with numerous institutions in Philadelphia and in Ireland, and spans more than half a century of monetary support, memberships, and various levels of personal involvement. Material consists of correspondence, invoices and receipts, and ephemera. Because of the tax deductions associated with many of McIlhenny's contributions, a significant amount of related material can be found in the "Tax files" subseries of the "Financial records" series. This subseries also includes material generated by McIlhenny's sister and by his mother, and corresponding files are titled as such.
