I can find no evidence that Pound has any siblings. He was born on October 30, 1885 in Hailey, Idaho and when he and his family moved to Pennsylbania. In 1898, his great-aunt took him on a trip to Europe. He loved Europe and later moved there where he spent the majority of his life. In fact, he self-published his first book of poetry, "A Lume Spento" when he lived in Venice. Then he headed for London and met William Butler Yeats, who he met regularly with. He also formed friendships with many leading writers of the time.
