"Almost the entire information we have concerning this man beyond what is stated in his father's will quoted above is found in the following deed..."
[Note: the deed is cited below. The father's will on p. 318, dated 1679, says "in case my son Thomas Underwood now in old England shall within two year after my decease come to abide and dwell here", in which case he was to get 6 acres in Cambridge. But the will of the widow of the father devises six acres Cambridge to her kinsman John Gibson, which suggests the son in England never came, i.e., this will describes a different man than Joseph's father. Note: this source, p. 322, gives a death date of 27 Apr 1760, but no such death date is found. A Joseph Underwood d. Lexington 25 Apr 1760 per Lexington VRs, but his record is identified as having "wid. Eunice", and the probate file for Joseph Underwood in 1760 shows a widow Eunice. The probate document naming children of Joseph and Ruth (no case number is given) has not been located.]
