The several record sources I have do not mention these children, BUT, anything is possible. "The Brockway Family, Some Records of Wolston Brockway and his Descendants" compiled for Francis E. Brockway, Owego, NY 1890. Appendix page 132. Mary Brockway; married with Joseph Earl. Daughter of Ephraim and Esther Calkins Brockway. "Brockway Vital Records of New Hampshire" compiled by Florence M. Brockway, Dorchester, MA 1950 page 83. Sally Brockway & Joseph Earl of Plainfield, m. Feb 23, 1789, Plainfield. (Daughter of Ephraim and Esther Calkins Brockway.) "Brockway Records. Data on Descendants of Wolston Brockway", collected and typed by Florence M. Brockway, Dorchester, MA 1949, page 81. Sally, b. about 1769; died April 26, 1844, @75y. m. Joseph Earl of Plainfield, N.H. Feb 23, 1789 at Plainfield (N.H. vital records). Brockway genealogy says it was Mary that married Joseph Earl. Addison and Lamoille Cos., VT Gazeteer. 1883 Joseph Earl came from New Hampshire to Morristown in 1801; married Sally Brockway of Walpole,NH. Joseph died aged 95y. Son Hiram resided here aged 83y.
