William Roberts and one of his sons-in-law were killed by Indians in 1675, during King Philip's War... From the account [of his estate] ... it appears that Roberts was survived by his wife and that his son, William Roberts, died before 1677...    The name of William Robert's wife is not known.     The number and names of William Robert's children are determined by the deeds disposing of the two hundred-acre town grants.  The property was conveyed in "one-fifth parts" by Elizabeth Allen, Sarah Harmon, Grace Moses and Hannah Cox, all stating that they were daughters of William Roberts.  This leaves only one fifth to be accounted for, and proves that at the date of the division no son of William Roberts was living to inherit a double portion.  The last fifth was held in shares, of which two were conveyed by John Sias and Ann, his wife, and one by Richard Denbow, on the same day, to Salathiel Denbow, who later conveyed all his rights in the property of his grandfather, William Roberts.  From these facts the theory is advanced that a daughter of William Roberts married, first, a Sias -- the son-in-law who was killed by the Indians with her father in 1675 -- by whom she had a son, John Sias, who inherited an eldest son's

The AF has William born in NH in 1614, but that would have put him here before the Mayflower!  The AF has him the son of Thomas ROBERTS & Rebecca HILTON, but Thomas is too young to be William's father.  The first we know of William is when he appears in NH in 1645.  It is far more likely he was born in England and arrived in New England during the "Great Migration" of the 1630s and 40s.
