“Senator Carew and his family have resided here for many years, and have been prominently identified with official and residential society. The old Carew mansion on Massachusetts Avenue east of Fourteenth Street has been noted for its lavish hospitality. It was erected by Senator Carew’s father, General Van Ness Carew, shortly before the commencement of the Civil War, and the foundations and walls were of such unwonted thickness that General Carew was pestered with inquiries as to whether he was not building a fortress!
