The Mutual Fire Insurance Company of Montgomery County used the Academy Hall for their annual stockholders meetings and alternate meetings of the Board of Directors (1857). The Academy Hall was also used as a meeting site by the Brookeville Lodge No. 50 of the Independent Order of Odd Fellows (I.O.O.F., also called Odd Fellows' Lodge). They rented the Academy Hall for the purpose of holding their meetings at $3 per month per year, subject to consent from the Mutual Fire Insurance Company (1859). The Lodge continued to rent the Hall until its lease was terminated and the Academy building sold to them by the Brookeville Academy Trustees in 1867 for $1,200.

Brookeville Lodge No. 50 I.O.O.F.
The new owner of the Academy building, the Brookeville Lodge No. 50 I.O.O.F., recorded a deed on January 11, 1870 in Liber E.B.P. 7, folio 86. The lot adjacent to the Academy was sold to the Lodge at the same time for $100 by Elisha J. Hall and Mary B. Hall, his wife. The Brookeville Lodge No. 50 I.O.O.F. continued to use the Academy building, then known as the Brookeville Memorial Hall, for its meetings until 1900.

Thomas J. Holland and John W. Whiteside
In 1900 the ownership of the Academy building and adjacent lot (Lots No. 55 and 56) changed hands. Since by 1900 the Brookeville Lodge No. 50 I.O.O.F. had resigned its charter, a deed (recorded March 19th, 1901 in Liber T.D. 16, folio 459 et. seq.) legally passed title from the Brookeville Lodge to the Grand Lodge of Maryland I.O.O.F.
