I have created an index to 3 books containing information on persons in Delaware but not having indexes. Having this information will help you decide if you want to come to the Library to look up someone in these resources. Or, if you are not nearby, you can request a copy of the relevant pages from the Interlibrary Loan service at your library.
These are the books:
Encyclopedia of Delaware. Santa Barbara, CA: Somerset, 2001.
Location: Morris Library F162 .E53x 2001
Hindes, Ruthanna. Delaware Silversmiths, 1700-1850. Wilmington, DE: Historical Society of Delaware, 1967.
Location: Morris Library NK7112 .H55
Location: Morris Library Special Collections Delaware NK7112 .H55
Wilson, W. Emerson. Forgotten Heroes of Delaware. Cambridge, MA: Deltos, 1969.
Location: Morris Library F163 .W54
I will be adding other sources as time permits.
