From what I have read, all peach trees are self pollinating ???
I like Ranger, Redglobe and Belle of Georgia

A fruit tree is a long-term investment. You might consider going to a local nursery to get some advice on the best varieties for your area. You are also more likely to get a peach grafted to a rootstock suited to your soil type from a local nursery than from Lowes or Walmart, which often make big purchases of trees for a very wide region.

While probably not really close to you, the fruit tree list below from Fanick's in San Antonio gives you some idea of things like chill hours, disease resistance, etc. which should be taken into account when chosing a stone fruit tree. I am intrigued by their August-fruiting peachcot.

Most, but not all, peaches and nectarines are self-pollinating. This is not true of many other types of fruit trees. Peach trees grow fast, and depending on the rootstock you could expect fruit in two to four years, with production declining as the tree reaches 15 or 20 years of age (sooner where certain diseases are prevalent).

You will get some good advice on taking care of fruit trees over at the Fruit and Orchards forum.

Here is a link that might be useful: Fanick's Fruit

This is from Texas A&M, East Texas is in area 2 Self Fruitfful means no more than one is need for pollination

Peaches are well adapted to most parts of Texas. Because all peaches are self-fruitful, it is not necessary to plant more than one variety. One tree normally supplies more peaches than one family can consume. The later ripening varieties are of better quality.
