Born in Connecticut, in 1858, she removed with her parents to Maine at a young age, with the greater portion of her life spent in Portland and vicinity.

While wandering among the wooded vales and hills near her home in a suburb of Portland, Maine, where the greater part of her life was passed, she perhaps unconsciously developed the latent poetry in her nature.

Thereafter, her poems and sketches appeared in various magazines and periodicals under the signature H. E. P., and her maiden name, Harriet E.

[3] In the year 1886, she married Ernest Warner Arnold, of Providence, Rhode Island, and made that city her home.

[3][4] Harriet Pritchard Arnold died August 4, 1901, aged 42, and was buried at Swan Point Cemetery in Providence.
