Bren [bren] as a girls' name (also used as boys' name Bren) is of Old Norse, Gaelic and Welsh derivation, and the name Bren means sword; little drop of water; raven or black-haired; hill. Bren is an alternate form of Brenda (Old Norse): related to the English word brand. Bren is also a variant of Brenna (Gaelic).
The origins of the Black Death can be traced back to the Gobi Desert of Mongolia in the 1320s. The cause of this sudden eruption of the plague is not exactly known. From the desert, it spread out in all directions. Of most importance was the spread eastward to China.
The plague is believed to be the cause of the Black Death that swept through Asia, Europe, and Africa in the 14th century and killed an estimated 50 million people. This was about 25% to 60% of the European population. Because the plague killed so many of the working population, wages rose due to the demand for labor.
