Raymond Hildreth Halsey, a farmer who owned the Green Thumb farm stand in Water Mill, died on Friday at home on Halsey Lane in that hamlet. He was 88. His family said he had heart problems.
One of the last of a generation of potato farmers who found ways to adapt to the changing times in order to stay in business, Mr. Halsey was a 10th-generation descendant of Thomas Halsey, one of the original English colonists of Southampton.
