Well, first you'll need to know the county where land is owned. Most records we genealogists want will be recorded at the county level, birth, deaths, marriages, wills, probates, land and tax records.
Right now most land records are not online. Occasionally you'll find some on a GenWeb site for a county. The GenWeb sites are manned by volunteers and some are loaded with information, others not so much.
Have you used GenWeb?If not go to -- http://usgenweb.org/http://usgenweb.org/ -- This puts you at the U.S. level, from there choose a state, and then from that level choose a county. Most will have a "search" feature where you can type in a surname and ask it to search what is on that particular site for that particular name.
Now there is also an archived site for each county, too. Don't ask me why, some will have basically the same information some will have different information -- http://www.rootsweb.ancestry.com/~usgenweb/http://www.rootsweb.ancestry.com/~usgenweb/ -- Again, choose a state then a county.
When using these sites, click and look at "everything." Sometimes I think people try to hide things from researchers, or maybe it's just because I'm not too computer savvy.LOL
For example on the TX GenWeb site -- http://www.txgenweb.org/indexb.htmhttp://www.txgenweb.org/indexb.htm -- This is the "old" site, apparently they are going to make some changes, but for now this one is still working. Look and click on Texas Research Help. It comes up wit huge list of other sites. One of my favorites from the big long list of other sites is "Postmasters & Post Offices of Texas, 1846-1930" It's good for looking up old post offices no longer in existence. I've seen people post queries saying they have an old letter but the town on the return address is one they can't find. Often I've found it on the this site and we can at least put it in a county. Hey with 254 counties in TX every little bit helps.LOL
So, how many other GenWeb sites have that much help hidden under a plain title such as Research Help?????
I don't know where you live, but if you give me the name of the county and state I'll look and see if I can find a genealogy society or library near you. Often you can find help from others near you. Our own society here in CA puts on classes and workshops to help with research.
