If your family is like everyone else, some part of your tree migrated to or from Texas or other parts west. Coincidentally, my ancestors on my father’s side all were in Texas at some point. There were many reasons people were drawn to western areas. A large part was due to the land they was undeveloped and free for the taking. The Homestead Act of 1862 allowed you to file a claim for land, plow it, dig a well live there and farm it for five years, It became yours. Other reasons to move west were the movement of railroads, cattle drives, gold mining and lack of farmland in the east. I am not certain the reasons for my ancestors going to Texas. I do know they left Alabama, went through Arkansas and Louisiana and ended up in the north Texas region known as Fannin county. And, I ended up in Alabama, go figure.
