Miller Christy , Dictionary of National Biography… (1888)
“ Doubleday was never married. He was throughout life a quaker. Among scientific men at large he cannot hold a high place; but, as a lepidopterist simply, he was, in the words of his friend Newman, ‘without exception the first this country has produced.’ He died on 29 June 1875, and was buried in the ground adjoining the Friends' meeting-house at Epping. His collections of British and European lepidoptera have probably never been excelled in their richness and variety. ”
