_Lord Halifax and Mrs. C. Barton_ (Vol. viii., pp. 429. 543.).--In answer
to J. W. J.'s Query, I beg to state that I have in my possession a codicil
of Mrs. Conduit's will in her own hand, dated 26th of January, 1737. This
document refers to some theological tracts by Sir Isaac Newton, in his
handwriting, which I have. On referring to the pedigree of the Barton
family, I find that Colonel Robert Barton married Catherine Greenwood,
whose father lived at Rotterdam, and was ancestor of Messrs. Greenwood,
army agents. His issue were Major Newton Barton, who married Elizabeth
Ekins, Mrs. Burr, and Catherine Robert Barton. I find no mention of Colonel
Noel Barton. The family of Ekins had been previously connected with that of
Barton, Alexander Ekins, Rector of Barton Segrave, having married Jane
Barton of Brigstock. The writer of this note will be obliged if J. W. J.,
or any correspondent of "N. & Q.," will inform him if anything is known
respecting an ivory bust of Sir Isaac Newton, executed by Marchand or
Marchant, which is said to have been an excellent likeness.
