Hamfast was the son of Hobson "Roper" Gamgee. He married Bell Goodchild, with whom he had six children, including Samwise Gamgee, his youngest son. He was a gardener on the Baggins property at Bag End for many years. He was frequently consulted for his knowledge of root vegetables (generally over a pint at the local inn), and was seen as a particular authority on the growing of potatoes. As the time of Bilbo Baggins's birthday party drew near, he was also in demand for his stories of Bilbo and his family. He didn't particularly like Sandyman the miller.
