Just to note an error on Elizabeth Brockway - she married George Hubbard on 24 Sept 1734 (this is according to Connecticut marriage records). This means she was most likely born about 1715.

Also I have information on Samuel Jr's 1st wife. My records show that he married Margaret Smith (d/o Joseph Smith and Margaret Brockway). They married 1 Nov 1743 in East Haddam and divorced 27 Feb 1759 in Waterbury. [Waterbury, CT Superior Ct; Inf: Am Gen, Jan 1953, Vol 30, p. 216 "Husband Samuel Brockway divorced Margaret Smith, who was "metnally distracted" in year 1758. Margaret had cohabited with a negro slave."
