Thocomerius "Toq-Timur", Prince of Wallachia ~1290-~1310
The name used is suspect. See detailed argumentation below.
Toq-Timur was born the son of Mongke-Timur who was the 5th Khan of the Golden Horde. Mongke-Timur ruled the Golden Horde from 1266 to 1282 when he died.
In Wallachia arose a Prince Basarab I who ruled from about 1310 to 1352 when he died. His father is called "Thocomerius". The speculation is that Thocomerius and Toc-Timur are the same person.
