Baptised 7/14/1605 at Saint Michael Paternoster, London (findagrave.com)
A May 5, 1695 document by Thomas Dunscombe, son of Philip and Joanna, indicates Susanna has died by that date with no issue (Composite Volumes of Deeds, etc., Vols. 3,1, p. 47 - Bermuda Archives). This statement of no living issue is repeated by Samuel Dunscombe, son of Susanna's sister Hannah, in his November 8, 1705 affidavit (Composite Volumes, 4,3, p. 199-200, Bermuda)
