Hannah the daught'r of Thomas Atkinson was borne the 5o. (1o) 1643. [Note: In old-styles dates, the first month is March. More info may be found here.]
Savage, p. 1:259, says Caleb Brooks m. (1) Susanna Atkinson, m. (2) "Hannah, sis. of the former w.". There does not appear to be any evidence to justify this identification of Hannah, and the age at death of the wife of Caleb Brooks, 70 on 10 Mar 1708/09, calculates to a birth about 1638, so is not a particularly good match. Marrying two sisters would have been extremely unusual (see wikipedia:Deceased Wife's Sister's Marriage Act 1907), so it seems very unlikely.
