Mrs. Amy Harlow (Lane) Waterman

Amy Harlow (Lane) Waterman, listed by Project Gutenberg as Mrs. Amy Harlow Waterman, 1873-, is remembered for compact household books written for children and young girls. The records readily available online clearly connect her with A Little Preserving Book for a Little Girl and A Little Candy Book for a Little Girl, both presented as simple instructional books with a warm, conversational style.

Her work fits neatly into the early-1900s tradition of teaching everyday domestic skills through storytelling. In A Little Preserving Book for a Little Girl (published in 1920 by Page Company, according to Google Books), she explains canning and preserving in an easy, encouraging way; Project Gutenberg also identifies her candy book as part of the same friendly "little book" approach.

Reliable biographical detail beyond her name form and birth year is scarce in the sources I could confirm here, so it is safest to see her as a lightly documented but appealing practical writer whose books were designed to make home cooking feel inviting to young beginners.
