Located near the Severn river north of Annapolis, Maryland, Severn Oaks Farm was founded by Dr. Elizabeth Iliff in 1947 with the purchase of a Section A Welsh mare, *Coed Coch Ebrill (Revolt x Coed Coch Eirlys), one of the few available for sale in this country at that time. In 1948, Miss Brodrick of the Coed Coch stud in Wales, gathered 9 mares for Mrs. Iliff for importation to Maryland. Several of these mares (*Coed Coch Pansi, *Coed Coch Serog, *Coed Coch Morfa, and *Criban Waaf), with Ebrill, became the foundation breeding herd for Severn Oaks.
Today, the Severn stud continues to breed quality Section A's Welsh under the management of Mrs. Iliff's daughter, Tiz Benedict. There are usually about 25 ponies on the farm with 2-7 foals born annually.
