"nor" and "niether" + sentence punctuation

Hi - I am having a great deal of trouble knowing how to punctuate the following sentence: "No one family, in their own name, is an army; nor can they withstand their enemies." The reason I have used a semi-colon instead of the coma is because I have comas before the word "nor" in the first clause. I thought this would read more easily?

I have been able to find, on the internet, that you usually use a coma with the word "nor"; and that "nor" and "neither" are usually used together. In this case, does the word "no" or "no one" act the same as "neither with "nor"?. Is the above sentence punctuated correctly? Thank you for your help, Chris
