Mcdonell of Pearl 1773

I am researching the extended McDonell family who left Scotland and arrived New York Province on ship Pearl 1773 .
I think I have figured out who the 6 Hostage / Prisoners were , that were taken from Sir John Johnson's in January 1776 .
Such noted EXPERT and Author W. L. Scott got that list WRONG . These guys survived the Rec War and settled in Canada .
