and try all 12 combinations of the names, just to see if you missed any. The LDS site uses a "sounds like" match, not "exact". I use it that way some times. They come up with surnames and given names I haven't thought of.
Another thing you might consider - visit or write to the library in the town you were born in. (If you write, send a small donation and a stamped, self-addressed envelope.) The library may have old phone books or city directories. If there is just one person there whose name matches any of the combinations from (1), you may have an exact spelling.
You may not. If your dad was "Burl Steel" and travelled a lot, living in cheap rooming houses, while the town had a "Burrell Steihl" who had lived there for 40 years and owned the bank, you'll have a false lead, since "Burl" won't be listed and "Burrell" will be.
You could find out what county you were born in and post a second request on the appropriate County forum. Texas is a big state.
Finally, most of us genealogy geezers consider all caps to be SHOUTING. Most of us avoid them on these query boards. Not all of us, and not always.
