John Fiske … m., Dec. 11, 1651, Sarah Wyeth, eldest child (only child by first wife) of Nicholas Wyeth, of Cambridge. … His daughters Sarah, Margaret, and Mary, received, at the age of 18, from Philip Smith, surviving executor of their uncle John Clarke, late of Newport, R. I., physician, deceased, legacies out of land on the Island of Cannonicut. June 2, 1684, George and Martha (Fiske) Adams received a similar legacy; each £3. 14.
These Clarke legacies confirm that Sarah (Wyeth) Fiske was daughter of one of the two surviving daughters of Thomas and Rose (Kerrich) Clarke of Westhorpe Suffolk. G. Andrews Moriarty, in 1921, identified Nicholas Wyeth, Sarah's father, as the husband of Margaret Clarke, but did not address the probability that Margaret had died before father and daughter emigrated to New England.
