As soon as the organization of Greene County was initiated in 1821, quick-witted landowners began to lay plans for securing a county seat on or near their property. Robert Hobson and John Evans were both interested in a site that would become Mount Pleasant. This location was only one-half mile from the current location of the Margaret Black Farmstead and very close to the other land purchased by Robert, James and William Hobson. From an article printed in the Carrollton Press in 1860, "Mount Pleasant was located on a beautiful mound in the midst of as fine a country as ever occupied a place on the map of the globe, in the prairie, just where a cool, shady grove or point of timber had found its way up the east side, nearly to its summit. From this elevated spot the eye delighted to range over the surrounding prairie to the north, the west, and the south, where the sides of the mound sloped gracefully down to the horizon, or to the dark groves of tall trees waving in the soft breeze."
Robert Hobson, who paid John Evans $50 to not bid on the property, acquired the property without an opposing bid and immediately marked out a town on the spot. He erected a dwelling and store house, opened a stock of goods suitable to the demands of the country, offered inducements to others to make their homes in the new town and in general manifested a commendable degree of energy, enterprise and business talent. Robert had registered a number of these lots in Margaret's name as well as in his own.
In anticipation of the arrival of his family the following year, Robert Hobson had several log cabins built in Section 28 of Carrollton Township at a location about 1/2 mile to the southeast of the later built Homestead house. The location was directly south of the mound called Mount Pleasant.
Robert Hobson expected Mount Pleasant to become the county seat of Greene County. He did not, however, take into consideration the anti-English sentiment following the War of 1812. When the vote was taken in 1821, only one person voted for Mount Pleasant since it had been laid out by "English" people. The site laid out by Thomas Carlin, a War of 1812 veteran, that later became Carrollton on February 20, 1821 was selected as the county seat.
On June 10, 1822 a party of 22 English people left Liverpool for America, including James Hobson (57), Elizabeth Hobson (43), Peter Hobson (13), John Hobson (6), Thomas Hobson (13), Mary Hobson (9), Robert Hobson (8), Jane Hobson (6), John Hobson (15), Margaret Black (51), John Black (19), David Black (17), William Black (15), Thomas Black (12), Elizabeth Black (12), John Armstrong (28), Isaac Richardson, Jeremiah Richardson, Elizabeth Richardson and George Beaty.
Thomas Black recalled the journey to America in his 1891 autobiography:
"We had a long and tedious voyage of forty-seven days across the Atlantic. When we first left
Liverpool, we got aboard an old vessel called the 'Niagara,' which proved unseaworthy and was
wrecked ten or fifteen miles out from port. We were then obliged to go back to Liverpool and get
another vessel, a brig called 'Yamacraw,' of which Captain Bates, a very good man from New York,
was master. In crossing the Atlantic we children had a good time, but with the old folks it was not
so agreeable, my mother and aunt being sick during most of the long voyage. The night we reached
New York (on July 22, 1822), a very heavy thunder storm came up, which my uncle said was the
artillery of heaven welcoming us to the land of liberty. He thought there was no such country for
freedom and liberty as the United States."
