Joseph Underwood [#4], s/o Joseph Underwood [#3] and Mary Wilder, b. Watertown 1650 [see attached comment], m. abt 1672 Elizabeth ---.
[Note: no basis for the birth estimate is given. This source notes that father's probate mentions children "evidently not mentioned in the order of their ages". However, the will of their uncle Thomas here may well reflect reflect birth order: Joseph, Mary (1645), Martha, Hannah, Elizabeth, Sarah, Thomas (1658). Based on a first child b. 1673, his marriage is estimated to be about 1672, which suggests he was born by 1651, but the uncle's will suggests earlier than that, perhaps about 1643 or 1644. Possibly Joseph is mentioned out of order, being the eldest male, but his legacy is no larger than the other siblings, so probably not.]
