Titus Tatius

Tatius had one daughter, Tatia, who married Numa Pompilius (Romulus' successor), and one son, who was the ancestor of the patrician Tatii family.

After a ceasefire, the nations signed a treaty creating a single kingdom under the joint rule of both kings, who reigned together until the death of Tatius.

Some escaped and when word got back to Rome, Romulus promptly arrested and surrendered the men responsible – including a member of Tatius' own family – over to a new group of ambassadors.

51–52 Dionysius also tells the account of Licinius Macer, wherein Tatius was killed when he went alone to try to convince the victims in Lavinium to forgive the crimes committed.

[7] Varro mentions him as a king of Rome who enlarged the city and established certain cults, but he may just have been the eponym of the tribe Titiae, or even an invention to serve as a precedent for collegial magistracy.

Gary Forsythe suggests instead, that Titus Tatius could well have been the first real king of Rome, who was later replaced in the accepted narrative by an unhistorical Romulus and Remus, whose names have been construed to derive from that of the city itself.
