|  | Abstract: | This collection is organized into two subgroups: personal and
		family papers from 1868 to 1927, most of which date from the late 1880s, and
		business records from the late 1880s to 1925. Most of the personal and family
		papers consist of clippings and invitations relating to the Deftys' musical
		interests, but also include a few family photographs and two
		diaries. |  |
