Odd that after searching for some time on the web and finally posting my query, I should find my own answer. Margaret, daughter of John Pierson, married Dr. Isaac Harris of Piscataway and Pitts Grove, NJ. She was his first wife, dying at age 34 in 1772. But I am still open to suggestions on who Molly Brown was -- Jasper Crane, Ogden, Johnson, Earle, Townley and Day families are my suspects, gathered from land holdings, naming, wardships, etc. WBB
