While I was reading blogs last night I came across this post: http://www.genealogywise.com/forum/topics/your-favorite-free-or-lowcost I always like something free or cheap and I hadn't heard of some of the sites listed in this posting.
I must admit that I have been extremely lucky in finding family history on the Internet. Admittedly most of it was on private websites and from people I made contact with through private websites but some of these sound worth a try.
I have a few elusive ancestors that must have been hiding out when the census taker came around and I swear whole families must have been stowaways when they immigrated.....or maybe they paddled over from Germany in a canoe!!!
