Siyu is a settlement on the north coast of Pate Island, within the Lamu Archipelago in Kenya's Coast Province. The age of Siyu is not known, but it might date from the 13th century. There are some other accounts that mention Chinese ships of Zheng He's fleet sinking near Lamu Island in Kenya in 1415. Survivors settled on the island and married local women. This has been proven recently by archaeological work on the island that has resulted in the finding of evidence to suggest this connection. Further DNA testing done on some residents from Siyu show that they indeed have Chinese ancestors.
