Most census records are not online, yet.Find out where researchers in your area go to look at the microfilmed copies of the federal censuses.Is there a genealogical society near you?Or, a Family History Center in your area, or even a NARA (Nat'l Archives Rec Administration branch) in your area?
I am going to give you some information on GenWeb sites, that I typed and saved in WORD - so I wouldn't forget parts of it.With this info, look for TX County Idx option, click on "F" and click on Franklin Co.Click on Enter, then wait for site to fully appear.On the right side among options is "Surnames", click on there, then click on "C".You will find someone else is working on Cain in Franklin Co, TX.It will give you an email, and you can contact them.I'll keep my fingers crossed their eddress is still good.If not, you can post a query, and maybe someone will recognize it.
I clicked on "Lookups", too, and you are in luck, they have volunteers listed to do 1900 census lookups.Go for it.Click and look at everything they have to offer on that site, and submit your surnames, too.
After reading the info below, if you have any questions, do not hesitate to respond to this site again.I will try to help, where I can:(^_^) ~~~~~~~~~~~~~~~~~ Texas began keeping vital records in 1903; you can obtain a copy of death certificate, which should show the names and birth locations of the parents of deceased.
Hyperlink below for TXGenWeb site.Scroll down to “TX County Index” option, find your county and click and look at everything.Sites are manned by volunteers, so they vary in material and information offered.Some will have a list of volunteers who offer to do lookups.Post your query; plus, ask if anyone has a copy of a county history, and will they check their copy for any possible information on your family.If cemeteries not online, ask if a collection of material, or book has been published on local cemeteries, and can someone check the index for you. http://www.rootsweb.com/~txgenweb/http://www.rootsweb.com/~txgenweb/
TX is a state with lots of good “stuff”, click and look, try “Texas Research Help”, it will lead you to such as:Handbook of TX Online (good for those TX towns not on maps, early settlers, history etc); Confederate Museum (all Rebs); TX Ranger Museum (both museums have records); TX Confederate Pension Idx Online (different then Museum); TX State Library & Archives etc etc.
When you finish with “ALL” of TX, look for the very first option on that site – USGenWeb Project – click and you are at the U.S. level, from there you can choose any state, and county/counties within those states – you are off and running, again.
