I'm afraid not, George, although there appears to be a substantial amount of information on Lynnewood Hall on the internet already. Excellent images too. This house was apparently one of Horace Trumbauer's finest and should really be conserved.
In an idle moment earlier this week I Googled Miramar, Eleanor Widener's 'cottage' at Newport, which was under construction at the time she, George and Harry sailed on the 'Titanic'. This spectacular property sold in December last year for a staggering $17,000,000.
