Baldwyn, Miss. “Lullaby.” Selections from Canadian Poets: With Occasional Critical and Biographical Notes, and an Introductory Essay on Canadian Poetry. Ed. Edward Hartley Dewart. [Montreal], 1864. 296.
I’m not sure if this “Miss Baldwyn” is Augusta Baldwyn (1822-1884), who also published in this volume. It seems unlikely that there would be two Miss Baldwyns publishing in the same volume, but also odd that one woman would be listed under two monikers. Augusta Baldwyn is the only Baldwyn we have listed at all, and did remain single throughout her life, so it is quite possible that this poem is hers.
