Street Directory for Glen Head area Nassau County. Agnes Clark. Francis A. Clark. Marguerite D. Clark. Stella I. Clark. These members of the same family were living together 1930 census. Agnes was listed as head of house, but address could be in any of the names. Please check Street Directory for 1930 Please check for Marguerite D.
