On 14 October 1842, he married
Cecilia Tennyson, daughter of Reverend George Clayton Tennyson, and younger sister of
Alfred Lord Tennyson, in Boxley, Kent, England. To mark the occasion Tennyson wrote as an epilogue to his poem
In Memoriam (1850), an
epithalamium (nuptial poem) on Cecilia and Edmund's marriage. Lushington remained one of Tennyson's closest lifelong friends, as well as being his brother-in-law. He had four children: Edmund ("Eddy"), Cecilia ("Zilly"), Emily ("Emmy"), and Lucy.
Edward Lear made many gifts to the Lushington children included an album containing drawings of birds, animals and landscapes, which he presented to Zilly on her tenth birthday in 1855. ==Notes==
