A property in Willistown Township owned by the descendants of William Rockefeller Jr. has been listed for $29.9 million, writes Kennedy Rose for the Philadelphia Business Journal.

The 210-acre farm at 944 Providence Road could potentially open another large swath of Chester County to developers.

The owner of the property is listed as Woodkirk and The Glenmede Trust. Its trustees include M. Roy Jackson and his children, who are Rockefeller descendants. William Rockefeller Jr., former president of Standard Oil, is Jackson’s grandfather. He was the brother of the founder of Standard Oil, John D. Rockefeller.

The property has not been on the market for nearly nine decades, according to Lavinia Smerconish, the broker who has the listing.

The parcel has no conservation easement, and its owners have not expressed any objections to the land being developed. Despite the asking price of more than $142,000 per acre, the property has already seen interest from both homeowners and developers.

“It seems excessive, but that’s only because the amount of ground being offered is a large amount of ground,” said Smerconish. “But it’s certainly not excessive when you look at what the product is.”
