Margaret named her dau. Ann after her sister.
m. Andrew AITKEN,
“Margaret’s younger sister Annie and her husband Andrew Aitken, were finished with Dunfermline, and in 1840 they emigrated to Allegheny City, a suburb of Pittsburgh. They arrived on July 2 and searched for Annie’s sister Kitty, who had emigrated there earlier with her husband, Thomas Hogan. The Aitkins and Hogans, including Thomas Hogan’s brother Andrew, then pushed on to Allegheny, otherwise known as Slabtown - a nickname less appealing and, perhaps, less inviting than Auld Grey Toun.” [”Carnegie, by Peter Krass, p.15:]
