DURHAM, N.Y. — Farmer Frank hobbled into the house, cane in hand.

“Sow got out of her pen, had to chase her down,” said Farmer Frank — Frank Hull, 71 — whose body, ravaged from decades of heavy manual work, is no longer built for chasing sows.

For half a century, he and his wife, Sherry, 67, have run their 260-acre farm here in the upper Catskills, some two hours north of New York City.

Known as Hull-O Farms, it has been in Mr. Hull’s family since his forebear, John Hull, founded it some 240 years and seven generations ago.

It is one of the oldest farms in the country continuously owned and run by the same family. But that lineage is about to end.
