The birthdates for William Jeffries' older children suggest an error somewhere--one child born in 1706 and the last before c 1765.I may have a better estimate of Thomas' birthdate somewhere, but before c 1765 is probably close. He died c 1829/30 as I recall, and apparently in K&Q; I was able to determine the names of his sons from the division of his estate as recorded in K&Q land tax records.
