In contrast with other members of the family who became ironmasters, Robert Foley became an ironmonger, that is, a person who organises the manufacture of finished ironware and sells it. In doing so he may have been taking over that aspect of his father's business, just as his older brother Thomas Foley had taken over their father's ironworks. Shortly after the English Restoration, Foley obtained a contract from the Navy Board to supply ironware to several dockyards.[1]
His house at Stourbridge and estate at Netherton in Dudley were given him by his father. He probably mined coal in his land at Yorks Park, near Netherton around 1660, but left others to extend mines into neighbouring land. However he bought the manor of Kenswick in Knightwick himself in 1669.[2]
