It is theorized (not proven) that she was a sister of John Henry Barrow because, interestingly, in Spitalfields Christ Church on Oct 18, 1807 there was a Frances Martha Barrow married to a John Green. This begged the question whether this could be a sister of John Henry Barrow, since John Henry and his wife Ann were to name their daughter Frances Martha.90 The parish of Spitalfields was immediately east of Bishopsgate Without, in Whitechapel, south of Bethnal Green.
