IT'S a match made in the Guinness Book of Records. The world's most married man celebrated his 85th birthday last Sunday by preparing for his next wedding - to the world's most married woman. Glynn ''Scotty'' Wolfe plans to unite in wedlock with Linda Lou Essex, 53, of Indiana. Wolfe has been married 27 times, and Essex is a veteran of 22 marriages. Both are listed in the record book as having the most monogamous marriages. However, Wolfe is also listed as having died in 1991. ''That was a surprise,'' Wolfe said. But he added: ''I've been in heaven all the time.'' Wolfe met Essex four years ago on a television talk show. Another TV show took them to Las Vegas 18 months ago, hoping to pair them up. But at that time Wolfe's divorce from wife No 27 wasn't final. So Wolfe said he gave Essex a diamond engagement ring to add to her collection, and made plans to marry her after she moves to California. ''It's a big decision,'' Essex said, adding that it would be difficult to leave her seven children and 17 grandchildren behind.
