Winnie Holden Wrenn, 93, a columnist for the Loudoun Times-Mirror in Leesburg for more than 30 years, died Sunday of cardiac arrest at the Hermitage of Northern Virginia.

Mrs. Wrenn lived in Herndon for 60 years before moving to the Hermitage in Alexandria in 1975. Beginning in the 1930s, she wrote a weekly column on news from Herndon for the Times-Mirror and other weekly newspapers.

She was born and reared on a farm called "Elsinore," which was located on the Bull Run battlefield near Centreville.

In 1915, she married Raymond N. Wrenn, a realtor, who later served as mayor of Herndon and on the Herndon Town Council for more than 20 years.He died in 1956.

Mrs. Wrenn was active in the Herndon Home Interest and Garden Club. She served as treasurer of the old Herndon Congregational Church and was a member of the Trinity Presbyterian Church in Herndon and St. James Methodist Church in Alexandria.

Survivors include three sons, the Rev. Raymond F., of Richmond and Middleburg, Va., Robert H., of Alexandria, and Thomas R., of Adelphi, 10 grandchildren and seven great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Hermitage of Northern Virginia in Alexandria.
