By 1417 Lorenzo Ghiberti was married to Marsila, the 16- year-old daughter of Bartolommeo di Lucca, a worthy comb-maker.[25] Together they had two sons. In 1417 they had Tommaso Ghiberti, and a year later they had Vittorio Ghiberti.[26] Ghiberti was wealthier than most of his contemporary artists, with his success bringing him great financial rewards. A surviving tax return of 1427 shows and he owned a considerable amount of land in, and outside of Florence. He also had a substantial amount of money invested in government bonds to his credit. Over the years, his real estate and monetary holdings continued to grow.[26] Lorenzo Ghiberti lived to be seventy-five years old, and succumbed to a fever and died in Florence.[1] He was buried on December 1, 1455, in Santa Croce.[1] Vittorio followed in his father's footsteps as a goldsmith and bronze-caster, but never rose to great fame.[1] Tommaso did join his father’s business, helping as a collaborator with Lorenzo's assistants.[25] After his father’s death it is unknown if he continued in the business, as he is not mentioned in any of the documents after 1447.[25] Later, Vittorio had a son in which he named Buonaccorso who followed the paternal art.[1] However, Buonaccorso had a different spin on his grandfather's work, with his metal castings taking the form of artillery and cannonballs. His manufacture of these weapons made him famous, mainly for supplying the wars of Sarzana and Pisa.[1]
