虽然懂什么意思，只是到了no less person than那里总是组织不好语言，只可意会不可言传的样子。大家看看能不能帮我翻译这句超长的句子。
Halley obtained such support from his father and from no less person than King Charles II who provided a letter asking the East India Company to take Halley and a colleague to St Helena.

Halley obtained such support from his father and from no less person than King Charles II who provided a letter asking the East India Company to take Halley and a colleague to St Helena.
此句译为：
哈雷从他父亲和不亚于查尔斯二世那样的大人物那里获得了帮助。查尔斯二世写了一封信给东印度公司，让东印度公司带哈雷和一个同事去了圣赫勒拿。

这里no less than 有不亚于，不次于的意思。
如：He is no less a person than a minister.
他的身份不亚于部长。
根据句意，翻成“不亚于查尔斯二世那样的大人物”更合情合理一点。
