The following information is a superficial genealogy of those mentioned in "Important": Elizabeth Kennard Robson's Tribute

     The note's author, Elizabeth Kennard Robson, was born in 1866. As of yet, her husband is unknown, She died in 1946 and was buried in Middletown Cemetery, Dauphin County, Pennsylvania. (Link to Find-A-Grave) 

     Robson's  Grandmother was Elizabeth (Newton) Cook (Feb 20, 1806-March 6, 1881). She is buried in Friends Meetinghouse Cemetery in Kent County, Delaware. (Find-A-Grave added "Dill" to her name. That name is neither on her headstone or in Robson's write-up, so I'm going to leave that alone.) Elizabeth (and, as of yet, an unknown fellow or fellows) had three children. Only two of the children are pertinent to this piece. 

      Armina Davis Cook Kennard was Robson's birth mother. Armina's birthdate is unknown. She married William Groom Kennard (1826-1898).* They had one child, the author of the "important" note, Elizabeth Kennard Robson.  Armina Died on December 18, 1870, when Robson was only four years old. Armina is also buried in the Friends Meetinghouse Cemetery in Kent County, Delaware. (Link to Find-A-Grave) After her mother's death it seems that Armina's sister, Mary, took over the care of the child. 

      Mary A. Cook Spencer was born in 1848. She married Leonard M. Spencer (1827-1914). Clearly, from Robson's note, the Spencers lived in Philadelphia. Yet, from information on found on Find-A-Grave, both Mary and Leonard are buried in the Friends Meetinghouse Cemetery in Kent County, Delaware. (Link to Find-A-Grave)

     Mary and Armina's sister was Susan B. Cook Pleasanton. She was born in 1828 and died in 1900. Her husband was Edward Pleasonton (1812-1894). They were buried in the Friends Meetinghouse Cemetery.(Link to Find-A-Grave)

      Isaac Newton (1643-1727). "Astronomer. English Quaker Stock." 

*Note he and Robson were both buried in Middletown Cemetery, Dauphin County, Pennsylvania. Robson's grandmother, mother, and Aunt were all buried in the Friends Meetinghouse Cemetery in Delaware.
