It is best to save this website manually, downloading each file one at a time.
Using Httrack to do it through the wayback machine is not the way to go. In
fact I will say that it cannot be (easily) done with Httrack.

I sent you a message volunteering to save your website from the wayback
machine for you. The reason I make this offer is because your old website is
small and I have saved websites of this size from the wayback machine before.
Keep in mind that even if you save the website yourself you will have to strip
each html page of the script that the wayback machine puts into those pages.

Two places to look for the website's files are below. One of the sites might
have files that the other site is missing. I don't know how the below links
will look until I post this, but the asterisk at the end of the URLs needs to
be included.

<http://wayback.archive.org/web/*/http://www.civilwarfamilyhistory.com/>*

I have already begun saving the website and have the majority of the files
saved already. If everything continues as it has I should be finished with it
tomorrow. If you would like the finished site let me know by replying to the
message I sent. I can send the site as an email attachment, but I will not
send an attachment to someone unless they know it is being sent.
