Huntington was born in 1742 in Lebanon, Connecticut, the daughter of Governor Jonathan Trumbull and his wife, Faith née Robinson.

Faith’s younger brother, Revolutionary era artist John Trumbull, credited her work as his inspiration: "She had acquired some knowledge of drawing, and had even painted in oil, two heads and a landscape.

[1] While many businessmen made large profits from their dealing with the army, the Huntington fortune suffered from Jedediah's long absence.

[1] Her brother John served as adjutant to the Second Connecticut Regiment, briefly as aide-de-camp to General George Washington, then as a brigade major.

[3] To support Hannah, the Huntington and Trumbull siblings planned a trip to Dedham, Massachusetts to reunite her with her husband, Joshua.

[1] Though at times she felt "calm tranquility and composure," they would eventually give way to "great and surprising pain and distortion.

"[2] Her brother John later said that she "found herself surrounded, not by ‘the pomp and circumstances of glorious war,’ but in the midst of all its horrible realities.

[3] She also wrote to him that she “[hoped] the Unhappy Dispute may be Put to an happy Isue [sic] truly before Winter or I know not how I Shall Live through So Long an Absence from my Companion.”[3] As these bouts grew worse, and as Jedediah, who was in Boston, did not feel he could leave his men, he and his mother brought Faith to stay with friends in Dedham, where he could visit her frequently.
