For about five years, she also served as editor of The Messenger, the official organ of the Colorado WCTU. She was also a member of Woman's Press Club, Woman's Public Service League, Denver Woman's Club, Equal Suffrage Association, and the Plymouth Congregational Church. she married Judge Theodore Hawley (1827–1911), of Fort Dodge, Iowa.
