Edward Walford, Dictionary of National Biography… (1893)
“ In 1852 MacCabe for a brief period renewed his connection with the Dublin press as editor of the ‘Telegraph’ newspaper; but he soon after retired from active literary work, and lived for many years in Brittany. He was a contributor to ‘Once a Week’ and to ‘Notes and Queries;’ and was also the author of many scholarly articles in the ‘Dublin Review.’ He died on 8 Dec. 1891 at Donnybrook, co. Dublin, at the age of ninety. ”
