She was with him as he started his law career in Portsmouth, New Hampshire, and then sought to improve their lives by settling in Boston on Beacon Hill.

[5] The marriage became imminent after Daniel moved to Portsmouth and he earned sufficient income to support them.

[9] As Daniel settled into marriage and established his law practice, his poor health from his youth improved and he began to look hearty.

Daniel set up his law practice and the family moved into a house on Beacon Hill.

[12] Daniel was often out of town for weeks and months at a time, litigating trials and pleading cases before the United States Supreme Court, writing regularly to stay in touch with his wife.

[13] The Websters and two of their children, Julia and Edward, moved to Washington, D.C. in December 1823, as Daniel served as a representative in Congress.

[14] When in Washington, she left a good impression of being a down-to-earth, attractive woman, of common sense.

For instance, when Gilbert du Motier, Marquis de Lafayette visited Boston, Grace was the hostess for the combined Thorndike and Webster reception.

The wife of British Naval officer Basil Hall, who could be hard to please, states that Webster held the most impressive dinners that she had seen in America.

[19] She wrote a letter to Daniel, "I have lost the art [of] managing children..." on March 10, 1825.

[21] Beginning in 1825, the Websters stayed with Captain John Thomas and his family at their home (later named the Thomas–Webster Estate) near the ocean in Marshfield, Massachusetts.

[23] Webster died in New York City on January 21, 1828, of a tumor in her lungs,[2][10] or tubercular lesion.

[23] She was buried in an underground crypt in Boston and the remains of her daughter Grace and son Charles were reinterred beside her.

Grace Fletcher Webster was a person of very delicate organization, both physically and intellectually, yet she was energetic, and when occasion required she exhibited a rare fortitude.

To her husband's welfare she was entirely devoted; she presided over his household with peculiar grace and dignity, and really seemed to live for him.

When he was at home she - sought his comfort and pleasure; when he was absent her thoughts, as her beautiful letters testify, were of him day and night.
