He worked alongside White leaders like Charles Sumner to integrate schools and fight for the abolition of slavery. Morris also had strong connections with Boston’s Irish-Catholic community, including Boston mayor Patrick Collins. And throughout his life, he maintained close relationships with his family, including his mother and siblings in Salem.
