But there was much to be talked of in marrying her; and the good-natured wishes for her well-doing which had proceeded before from all the spiteful old ladies in Meryton lost but a little of their spirit in this change of circumstances, because with such an husband her misery was considered certain.
这里such an husband 是不是与an hour相同的情况用an？关于句子成分，which has proceeded中的which是good wishes的定语从句吗，那这个定语从句到哪里结束？到circumstances 还是到in Meryton?请给解释下，十分感谢

the good-natured wishes for her well-doing都是which指代的内容，which had proceeded before是定语从句，到这就完事，后面from是另外一个介词短语修饰前面名词，lost是谓语，but是除了。
such an husband这个，因为作者是100年前的，现代语法已逐渐不这么用了，那时候为啥这么用，不清楚，个人觉得不用深究
