General Notes

King Yakubher's throne name (seen within a cartouche in picture right) means - "Strong is the Love of Re". Practically nothing is known from the reign of this king (sometimes called Yakobner) and it's doubtful if he has left any remain beside being mentioned in king list written 1500 years after his time on the throne.
His Aramean name is related to biblical Jacob, and has made some groups see this as "evidence" that the Hyksos people were the Israelites. He is by some thought to fit into the many gaps in the 14th dynasty along with 11 other rulers with Hyksos names not present in the Canon of Turin. He seems in that case to place at the end of that dynasty.
If he is from dynasty 15 his reign might be 8 years around 1634-1626 BC.
His remains are from scarab-seals only (about two dozens) found mostly in Egypt, but also a few from Palestine and a single one from Nubia in the south.
