The Earl and Countess Cowper had several estates around the Home Counties and on their deaths, as they had no children themselves, their properties were distributed to various related families. Panshanger, the largest and the Home estate, was left to the Earl’s niece, Lady Desborough. It is not known whether any legal documents conceding the upkeep etc. had been drawn up by Countess Cowper, or were even awaiting signature on her return. However, Lord and Lady Desborough honoured her intentions, in regard to the Memorial Hall, in paying not only for a resident Caretaker but also for its maintenance and running cost.
During the Great War two of their sons were killed in action and the other in a motor accident in 1922. The estate passed to their two daughters but as death duties had increased astronomically during the following years, many parts of the Panshanger Estate were sold. These included all the tenant farms, Cole Green Estate Works, the large kitchen gardens, and areas of land on which part of Welwyn Garden City was built. Mr Julian Salmond, grandson of Lady Desborough, inherited the remainder which included the Village Hall in Panshanger.
On 3rd March 1954, the building, now sporting the name "Mayflower Place", was purchased from Mr Salmond by the East Hertfordshire Lodge. This was thanks mainly to the efforts of of W Bro Frank Wentworth Lawrence; a Past Master of the Lodge. The first meeting of the Lodge at Hertingfordbury was on Thursday 8th November 1956. It had previously met at Shire Hall, Hertford.
