His Lordship's Kindness, also known as Poplar Hill, is a historic plantation estate on Woodyard Road east of Clinton, Maryland.

The five-part Georgian mansion retains a number of subsidiary buildings including a slave's hospital and a dovecote.

The son in turn left the property to two nieces, Susan and Ellen Daingerfield of Alexandria, Virginia, in 1853.

The main block features a projecting bay containing the recessed entry door with fanlight, pilasters and pediment, and a large Palladian window on the second story.

The rear, or garden elevation is similarly composed, but lacks the projecting bay, and the door is less elaborately detailed.

The center hall is bisected by a wide arch, with the main stairway to the rear on the east side.
