The Atok herd of British Friesians was formed after Stephen and Gretta Jones (Roddy's father and mother) were married in 1943 when they took on the tenancy of Westbrook Manor, Dorstone, Herefordshire. A few years later (about 1946-47) the first pedigree cow was purchased. Milk recording was started a few years after that and the odd pedigree cow purchased among a majority of non pedigree. Stephen didn't believe in borrowing money and bought what he could afford. It wasn't until the late 1950's when a cow, named Tarbig Alison 3rd was purchased for 57 gns that the pedigree herd really took off. She had 4 heifer calves at Westbrook and there were no fewer than 34 cows tracing to Alison in 1983.
Roddy and Libby took over the farm and Atok prefix in 1981, when Stephen and Gretta retired, expanding the farm and diversity of animals and moved to Highfield in 2004.
