Documentation of some of the writings of Kimball's wife Marie comprise the bulk of this subseries and make evident the couple's shared interests in topics such as Thomas Jefferson and colonial architecture. In addition, Marie also published works about colonial and regional cooking. Her unpublished writing of Belmont, one of the colonial homes located in Philadelphia's Fairmount Park, appears to have borrowed heavily from Kimball's Belmont article published in a 1927 Museum Bulletin. Another collaboration of sorts is the manuscript entitled, "The House on the Mountain." Kimball wrote this piece for Marie's use in her book "Jefferson: The Road to Glory: 1743-1776," which was published in 1943. According to a 1941 note filed with the manuscript, Kimball wrote this as a "valentine and tribute" of his wife's contributions to his 1916 book, Thomas Jefferson, Architect. Although Kimball claimed that the manuscript served only as "raw material," Marie did borrow many passages, as a comparison of text proves, and she kept Kimball's title for that of her eighth chapter.

Also included in this subseries is what appears to be a preliminary outline of a book about Frederick Law Olmsted, which his sister Theodora co-edited. There are also a few miscellaneous typescripts authored by others and reprints, annotated by Kimball, of articles by H. Langford Warren and A.J. Penty. For the latter, Kimball resorted to a few critical interjections of "Oh!" "Blah!" and "Bunk!" The reprint of Mary Kane's 1956 article of James Westhall Ford is included here since she relied on the research Kimball compiled for his article on the same artist.
