The Conways brought over a number of English and Welsh families, who settled on the estate, and intermarrying with the natives, a race of sturdy yeomen soon sprang up.

The Conways were good landlords, and greatly beloved by the people.

With the addition made to the property the king conferred upon the fortunate recipient of his bounty the title of Baron.

At the close of 1627, Lord Conway began the erection of a castle (finished in 1630) on a picturesque mount overlooking the Lagan, and commanding a view of the hills of Down.

During the struggles of 1641 the castle was burned down, together with the greater part of the town, which up to this time was called Lisnagarvah, but thenceforth it received the name of Lisburn.
