Helen Mary Boyd was born in
Guildford, Surrey, England in November 1947 to Diana Frances Boyd (née Drysdale) and Colin "Jock" Ian Langdon Boyd, a pilot. As a rock star muse, Boyd inspired
Donovan ("
Jennifer Juniper") and
Mick Fleetwood to write songs about her. In July 1968, she and Pattie opened a boutique in London's fashionable Chelsea Market; they named it "Jennifer Juniper" after Donovan's
song of the same name. Boyd managed the shop, which sold antiques and other ''objets d'art'', while Pattie was the buyer. She wrote, or co-wrote, two songs for the band
Fleetwood Mac, although the group's manager gave the writing credits to her husband,
Mick Fleetwood. Boyd attended
UCLA in the late 1980s, earned a
PhD in
psychology, and became manager of an addiction treatment clinic. She co-authored a book about music and psychology, titled
Musicians in Tune. She spent many years running an addiction treatment centre in England. ==Personal life==
