This is an image of "Happy House," a wedding present given that name by John (US3405) and Gwen Mackay (US3405spouse1) at their estate adjoining Harbor Hill. A rambling dwelling, it was based on sixteenth century prototypes in England’s Cotswold’s and was designed by John W. Cross, of Cross & Cross. The J.W. Mackays left this house, for historic 'Matinecock Farm' in Lattingtown in 1957.
