Dear Archie, There is a RootsWeb reference about Ira W. Ackley which says Ira Ackley married "Mary Seabrook, a descendent of the English family who settled Seabrook Island." Robert Seabrook who died in 1720 was the son who settled Seabrook Island (not Edisto Island). Much of his Seabrook Island land went his brothers, because Robert married Mary Whitmarsh, "by whom he had no issue". It is likely that Mary Seabrook Ackley was the daughter of Joseph Seabrook (1700-1743) who married Elizabeth Whitmarsh. They had a son John Seabrook (1731-1783) who may be the namesake for John Seabrook Ackley born 1835.
