The Writer of the Will
In Will and Testament, Whitney's speaker is writing her will, and in doing so discloses some aspects of her character. In this poem we learn about her fondness for London, which she describes in great detail. We also learn that she isn't wealthy, as she describes herself as being "very weake in Purse."
The independent woman
In her second book of poetry, Whitney's voice transforms from a heartbroken woman to a woman who has become independent. She cites her singleness as the reason she has more time to focus on her writing: "But till some household cares me tie/ my books and pen I will apply."
Whitney's sisters
Whitney often mentions having younger sisters in her poetry, who are described as working in London in service roles. As readers, we get the impression that she cares greatly about her sisters and wishes the best for them. She often writes directly to her sisters, offering them advice. For example, in To her Sister Mistress A.B, she writes to her sister Anne.
London
London is often mentioned in Whitney's poetry. She explains in Will and Testament that she "there was bred," which is why she is particularly fond of the city. In this poem, she vividly describes the vibrant streets of London, from haggling with store owners, to its loudness and terrible smell. Her descriptions of London are often comical, making it seem like a humourous character in her poetry.
