It is an American history story.
The second most important hint is text about Morriss house.
he leased for a term of years the Washington Hotel, known now as the Arlington.
The point is, big portion of text is about Robert Morris (1734 – 1806). He becoming known as the "Financier of the Revolution".
What we know about Morris from Wikipedia?
In 1790, President George Washington accepted Morris's offer to make the house his primary residence; Morris and his family subsequently moved to a smaller, neighboring property. By the 1790s, Morris had become close friends with Washington, and he and his wife were regular fixtures at state events thrown by the president. The President's House, as it became known, served as the residence of the president until 1800, when President John Adams moved to the White House in Washington D.C.
Well. Let's change two words from cited sentence.
he leased for a term of years to Washington family, known now as the Arlington.
So we see that terms 'Morris house' and 'Arlington' are in tight connection. In fact Custis/Washington family bought property in Arlington in 1778.
Interesting picture is here. All 3 persons are mentioned in the text. Am I right, Franklin? :-)

There is number of others, not so important hints.
1. Morriss/Morris wife. See text about 'Miss Sarah Mitchel' and about MARY WHITE MORRIS (1749 - 1827);
https://www.librarycompany.org/women/republicancourt/morris_mary.htm .
2. Morriss/Morris place of birth. Maryland/England. Maryland - land of Henrietta Maria, the French-born queen of England.
3. Transferring of Morriss/Morris. Morriss was born in the State of Maryland, but removed at an early age. Morris left England to join his father in Maryland in 1747 (age of 13).
4. Chief Justice of the United States John Marshall (1755 – 1835) has visited Morriss/Morris house for sure.
Peter Viemeister is right. The author of this pamphlet is Ferdinand Charles Hutter (1831 – 1885), former CSA member. Part of text is about himself, like 'purchaser and shipper of tobacco in Lynchburg'
or connection to former CSA member, Lynchburg Mason leader Max Guggenheimer;

Another part of text is about real person - Robert Morriss. I don't bother you with Robert Morriss facts. It is useless.
In addition, every sentence about Beale is a bullshit, but treasure is not a bullshit.
In next message next week I gona talk about first most important hint, about words 'enumerated' and 'renumeration'.
