Mount Dillon

The estate was built around the 1770s by a Daniel Carroll. Carroll had leased adjacent land by the estate which he named Dillonsfield, which became Johnnycake Town by the early 19th century, now also in Catonsville. To the west, large swaths of land were also owned by his brother Nicholas Carroll.^[1]

The estate of 400 acres was listed for sale by Carroll in The Maryland Journal, and the Baltimore Advertiser in 1794.^[2] It was being rented out by an Ann Carroll in 1828.^[3]

Mount Dillon was owned since 1846 by Samuel Kirk Crosby and still had its old slaves' quarters when Crosby arrived.^[1][4] He engaged in farming for over half a century, and died at the estate in 1911.^[5] Portions of the estate's land were sold in the 1910s by his children,^[6][7] and the reduced estate of 272 acres was ultimately sold to Dr. H. M. Rowe in 1919.^[8] The Mount Dillon estate's mansion was demolished in 1959 and the estate's land became part of the Westview Park housing development.^[9]
