From the record
“Among the first Catholic families who settled in and around Mount Vernon were the brother's, Timothy and William Colopy, (1814), John P. McArdle, David Morton, William Brophy, Charles Colerick, and at a later date the families of Michael Boyle, (1835), Thomas McMullen, (1840), and Probably the earliest Catholics in this section of the State were those who settled at or near Napoleon, Holmes county, the settlement being known in early times as the "French Settlement;" and those who settled around what is now known as Danville in Union township.”

This property is in Mount Vernon, which the
county-history sources cover in 1 chapter of its own rather than as
part of a township. All are public domain and reproduced here complete.
Regional context, not property-specific
evidence. Museums hold 637 specimens
collected within 10 miles of Round Hill between 1837 and
1975: 574 Animalia, 37 Fungi, 25 Plantae, 1 Protozoa. 12 distinct Species records are shown.
Collected by A. Hall, A. P. Morgan, Andriessen, H. and others. Each is a
physical object with a catalogue
number, and each entry opens the museum's record. This is what was
collected and kept, not a survey of what lives here - nothing can be
concluded from a species being absent.
Regional context, not property-specific
evidence. The federal mineral resources record lists
4 workings within 5 miles of Round Hill: 2 past producers, 2 producers.
2 still produce. What was taken out: Sand and Gravel, Construction. Distance is straight-line from the
map coordinates, so a quarry counted here may appear on a neighbouring
settlement's page as well.

Mount Vernon, the town this property stands in, in 2 storm reports between 1995 and 1995: 1 thunderstorm wind, 1 hail.
The reports record 1 injury. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
A downburst with winds as high as 90 mph downed hundreds of trees, some on structures and vehicles. Signs were blown down and some windows were broken and minor roof damage occurred to several buildings. A dog was electrocuted when a live power line fell onto the dogbox. A man was injured by a falling tree limb and another man, sleeping in his bedroom, escaped injury when a large limb crashed through his ceiling missing him by inches. Three state highways where closed until storm debris could be removed, one for over 24 hours.
Large hail fell. A 41-year-old man was struck by lightning while working inside his new home which was under construction. The house appears to have been struck first and the charge passed through the man causing minor burns.

When this property was proposed for the
National Register, someone wrote the case for it: what the building is,
and why it matters. That document is a federal record in the public domain.
It is quoted below word for word, never summarised. The text was read off the scanned case file by machine, so the
occasional stray character is the recogniser's and the 1970s
typewriter's.
