He and his wife, Lydia (née Boggs) Shepherd (February 26, 1766 – September 29, 1867), resided there on the grounds of their plantation.

The Boggs Family migrated from Back Creek Valley, Frederick County (later Berkeley County), Virginia (now West Virginia), and John Boggs staked his claim to an area of land lying along a creek (which is a tributary of the Ohio River) just south of Wheeling in 1774 where he settled with his family.

Most notably is the Elm Grove Stone Arch Bridge, which was built by Moses Shepherd over Little Wheeling Creek in 1817 and is still in use today.

Every year, Moses and Lydia Shepherd traveled to Washington, D.C., and met many famous politicians and presidents of their time.

Daniel Cruger, fourteen years her junior, was a United States Congressman from Steuben County, New York, and they had met in Washington, D.C., during her many trips there with her first husband, Moses Shepherd.

Daniel Cruger died suddenly of apoplexy on July 12, 1843, at the age of 62 during a bank meeting in Wheeling.

Lydia Boggs Shepherd Cruger lived the last twenty-four years of her life in solitude in the mansion (a few of her slaves remained on the plantation to care for her), occasionally receiving visitors and relatives eager to hear first hand accounts of Wheeling's history.

The Osiris Shrine Temple purchased Monument Place after the 1926 death of Lucy Loring Milton and retain ownership to the present day.
