etymology - Where do the words for daughter, son, aunt, uncle, mother, father, cousin, nephew, niece come from?

Please see Title. I'm not specifically referring to which language they came from... but if they come from something else. In other words, do they come from words with other meanings.

For example, do words for children come from a word that means "being that comes from one's loins" or something.

Answer

I extracted the following from the online Webster Dictionary. It's interesting to see how all these words were transformed from Latin/Greek/Old High German/Middle English to the current English words.

Note: I know that this does not exactly answer your question, since you actually want to know if the words derived from words with other meanings. But I think that having the full list of originating languages here may be useful as other answers to your question may refer to it.
