There are at least two theories of the origin of the British White Cattle. One theory suggests that they was brought to the United Kingdom by the Roman's in 55 B.C.E. Another suggests that they were in the U.K. in pre-Roman times, possibly as long ago as 2000 B.C.E. One of the oldest herds of British White Cattle was the Sommerford herd. It was owned by Sir Walter Shakerly in Cheshire and established in 1725. In 1940, the British Government ordered the shipment of a group of these cattle to North America to safeguard a precious national heritage if the United Kingdom was invaded. This was the only breed to be safe guarded in this manner.
