surname, state in today's Hebei
邢 is a proper noun used as a surname and as the name of an ancient Chinese state in present-day Hebei. It does not carry a general standalone meaning.
邢 is a phono-semantic compound combining 开 (possibly a phonetic element) with ⻏ (阝, a mound or city wall), suggesting a place name. The exact historical development is uncertain.
The left side 开 looks like a gate, and the right side ⻏ is a city wall. Picture a gate in the city wall of the ancient state of Xing, which gave its name to a family.
For ケイ, imagine a person named Kay standing at the gate of the ancient Xing state: Kay -> ケイ.
