Estelle M. H. Merrill (née, Hatch; pen name, Jean Kincaid; September 30, 1858 – July 29, 1908) was an American journalist and editor of the long nineteenth century.

[1] A lover of nature from her girlhood, when she used to wander through the Maine woods, during her periods of teaching in the grammar and high school grades at Hyde Park, she was fitting herself at the Harvard Annex and with private teachers to take a professorship in botany, her favorite study.

Journalism became such a fascinating occupation that, though she was offered a lucrative professorship in botany at a Southern college, she chose to remain in the newspaper field.

[5] Merrill served as co-editor, with Dr. Mary Wood-Allen, of American Motherhood, a Boston magazine devoted to the interests of mothers and home-makers.

[6] On October 1, 1887, she married Samuel Merrill, a native of Charlestown, New Hampshire, a member of the Suffolk County, Massachusetts bar, and of the editorial staff of the Boston Globe.
