[1] The eastern boundary originates with the establishment of the former Metropolitan Branch of the Baltimore and Ohio Railroad in 1873,[2] creating the physical barrier which today separates Edgewood from Brookland to the east.

[4] The combination of her father's death, the Panic of 1873, and her divorce from William Sprague in 1882 put Kate into dire financial straits and unable to maintain Edgewood.

There, she sought to secure funds for Edgewood under the guise of preserving it as “a historic landmark in appreciation of the value of her father’s public service.”[5] She endeavored to persuaded Henry Villard – a powerful journalist and financier from the Chases’ past – to arrange a group of donors to support the estate.

In addition to Villard, backers included notable individuals like J. P. Morgan (of today's JPMorgan Chase, for whom Kate's father is a partial, historical namesake), Collis Potter Huntington, and Levi P. Morton.

The group established a trust fund in the amount of $80,000, which was sufficient to bring Edgewood out of foreclosure and to provide Kate a small stipend for a few years until the estate could be sold for a profit.

Kate's daughters Ethel and Portia subsequently shuttered Edgewood, and went back to their respective homes in Brooklyn and Narragansett Pier.

[4] In 1900, having outgrown its original 10th and G location, St. Vincent's Orphan Asylum for Girls purchased Edgewood and moved operations to the vacant estate.

The Metropolitan Branch Trail travels through Edgewood on its way from the transit center in Silver Spring, Maryland to Washington Union Station in the NoMa neighborhood.
