Taken from the Jannetje Vroom Bible in the museum of Old St. Edward's Church, these are the only known records of Isaac's birth and death.

Isaac probably farmed in Jamaica on his father's land. Like his father and brothers, Isaac was a Loyalist, appearing on lists of men who swore allegiance to the King in 1775-76, and on a list of Jamaica inhabitants who promised to assist in raising Loyalist troops in 1777.1 Isaac and probably his apparent brother Gerrit died while the Revolutionary war was being fought, and it's possible that they died in service to it.
