_Mrs. Catherine Barton_ (Vol. iii., pp. 328. 434.).--When I answered
the Query, I was not aware of what Baily states in the Supplement to
Flamstead, p. 750. Rigaud ascertained for Baily that Mrs. C. B. (the
title _Mistress_ being given at that period to marriageable young ladies)
was not the _wife_, but the _sister_ of Colonel Barton. Both were the
children of Hannah Smith, Newton's half-sister, and Robert Barton. Mrs.
C. B. was born about 1680.
