Thomas presumably trained under his father but neither gained their freedom of the Clockmaker's Company. Daniel Grignion was based close to the eminent Quaker clockmaker Daniel Quare and worked for him in some capacity (most likely some form of informal journeyman) hence after Quare's death in 1724 he made use of the goodwill associated with Quares name. Thomas joined in partnership with his father in around 1730 and then worked alone in the business from around 1750. Daniel Grignion died in 1763 and Thomas in 1784.Although relatively little is known about the Grignion family surviving examples of their work is generally of unusually high quality.
