I am descended from John Murdock (d. 1690) and Mary Munser (Munsen?) of Limerick, Ireland. Thier children were Peter, Dorcas, Abigail and Elizabeth. Peter (b. 5/6/1679 - d.1753) married Mary Fithin in East Hampton, Long Island. We think Johns ancestors were from Scotland... let me know if we're connected! I have extensive information on my line from John onward if any other Murdock's seem to be of this line.
