Thomas Gustavus Davis -- Beverly Town Records records his death due to "fever" at "Batavia". (Batavia, NY?)
According to the Vital Records of Gloucester Daniel was baptised 7 Dec 1800. This date is surely an error. ("Daniel Rogers, s. Josiah, bp. Dec. 7, 1800. CR2")
Thurlow is the generally accepted modern spelling of the surname.
