I don't know you, but saw Shirley's birth listed, and that's how I knew you have an aunt named Shirley.
Read first sentence in previous response, obtain death certificate for Joseph, it should have his parent's names.
Then the paragraph telling you about Tyler Co, TX GenWeb site, look for cemeteries.Emma is probably buried next to Joseph and you can get her death date, then a copy of her death certificate, which should show her parent's names.
Don't forget to talk to members of your family.
If you're just beginning maybe you are unaware of GenWeb sites.Here is something I typed and saved in WORD, so I could just copy and paste, otherwise I might forget parts of it. (^_^)
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.
