Richard was a noted housewright and architect in Newport.
Boston records refer to a Richard Munday in Boston, winecooper, who had a wife named Martha in 1728.
The dates for his five children are baptismal dates from St. Michael's Episcopal Church in Bristol, RI. I don't know if they were actually born in Bristol or in Newport.
A Plymouth, MA, court record of 1736 mentions Richard Munday "Bristoll yeoman or Houswright" in a court case involving a cow that was not returned by him to the plaintif, Otiss Little, gentleman of Pembrooke.
The will of Richard Munday of Newport, housewright, dated 1738, mentions his wife Elizabeth and 5 children: William, Nathaniel, Richard, Mary, and Rebecca. No grandchildren are mentioned (it appears that he died when his children were very young).
