A member of this family replaced Richard Chenevix Trench as the first editor of the Oxford English Dictionary after the latter was appointed Dean of Westminster. A poem asks a member of this family “What hast Thou to do with sorrow / Or the injuries of tomorrow?” and refers to that person as “a gem that glitters while it lives.” A poem addressed to a member of this family hopes for him to “wander like a breeze / By lakes and sandy shores” and declares that “all seasons shall be sweet” to that infant. That poem, which opens with a description of its title phenomenon’s “secret ministry,” is one of the “conversation poems” by a member of this (-5[1])family. For 10 points, give this surname of the author of the poems “Frost at Midnight” and “Kubla Khan.” ■END■ (10[1])
