On 29 May 1717 when Margaret was 20, she married William Fletcher in Brattle Square Church, Boston. Born in England.
There were apparently two or more different families, William and Margaret Fletcher, living in Boston at the same time. One family could not account for the births of all the children of William and Margaret that appear in the Boston records. Some of them were baptized at the Brattle Street church by their mother Margaret Fletcher and were, no doubt, the children of William and Margaret (Cushing) Fletcher who were married at that church in 1717.
