Ian MacKechnie and family
Glasgow-born MacKechnie, 73, made his first fortune building up a wholesale bakery business and selling it in 1975. He followed that with a cafe chain, bought by the Ladbroke Group 10 years later. Then he relocated to Florida where he founded Amscot, a financial services operation with annual revenue exceeding £177m and profits of £30m. The business, owned by the MacKechnie family, is worth £212m. A generous philanthropist, he has donated more than $430,000 to charity in the past year.
