Susanna Potter emigrated to New England in 1634 and settled in Portsmouth, Rhode Island. She married John Anthony, son of Dr. John Anthony. He was born 1607 in London, England. He took the Oath of Allegiance in 1634, and sailed for America on the Hercules, settling in Portsmouth, RI. The American branch of the Anthony family is descended from John Anthony and Susanna Potter.

needs-Research: Susanna wife of John Anthony is probably Susanna Unknown. John potter (son of Robert) called John Anthony his uncle leading to Susanna being (Potter) but also to Isabel wife of Robert Potter being called (Anthony) Neither has been proven but there's an article in The Genealogist 4:60 that supposedly explains this.
There were numerous immigrants to colonial Rhode Island named Potter and there may (or may not) have been ties of kinship between some of them. Once upon a time, several Potter immigrants were erroneously identified as children of George and Martha ([-?-]) Potter of London in the research of Vernon and Nola (Steed) Valantine of La Crescenta, California, as submitted to the Ancestral File of The Church of Jesus Christ of Latter-Day Saints. In 1999, another researcher, Paul Gifford, reviewed the relevant parish registers and discovered that most of the birth records thought to pertain to the immigrant Potter siblings actually had corresponding death records! The origins of the Potter immigrants and their kinship, if any, remain unknown.
