Moreton Frewen was an economist and M.P. for North-east Cork. He married Claire (Clara?) Jerome, elder sister of Jennie Jerome (Winston Churchill's mother), and built a large house, Frewen's Castle, for his new bride, including papered walls, English woodwork, a piano from Chicago and telephones. The isolation and a miscarriage were too much for Clara, however, who returned to New York within a year.
Frewen appears to have been known to JW in the mid to late 1880s. This was a time when JW certainly cultivated the acquaintance of a number of M.Ps, perhaps as potential patrons, or to make useful contacts. However, it may well have been his long-standing interest in Irish politics that formed the bond between them. Frewen resigned in 1911 to leave the way clear for the election of a Nationalist.
Later Frewen became a rancher, cattle baron, and millionaire in Wyoming, in partnership with Sir Horace Plunkett in the Powder River Cattle Company.
