Brahmans were already in the United States because that's where the breed was developed. So Brahman cattle would've been in a few places in the South (besides Texas) when and after the breed was being developed in the early 1900's.
Brahman cattle are a breed of Zebu cattle and were the first American cattle bred for beef. Their habitat is mainly that of any other cow in America - the Brahman can handle most weather and is relatively hardy to the elements. It lives in pastures on farms.
The first cattle that Columbus brought over were in the real southeastern part of the United States (or the New World as Columbus called it), which would be now Florida west to Louisiana, before they spread into what is now the state of Texas. These cattle were shipped over from Spain to the New World.
The Santa Gertrudis cattle was originally bred at King Ranch, in Kingsville, Texas. Santa Gertrudis cattle are a cross of Brahman and Shorthorn.
The first American-created breed of beef cattle would be the Texas Longhorn and also the Florida Cracker/Pineywoods cattle. Both breeds descended from the Spanish cattle that were imported from Spain in the late 1400's.
Cattle drives originated from where cattle were first domesticated, which was in and around Egypt, Middle Eastern countries, and into Spain, well before cattle were first introduced into the New World in the late 1400's.
This would depend upon the relative size of the Jersey and the Brahman in question. Jersey cows are among the smaller breeds of cattle, and Brahman bulls tend to be among the larger breeds of cattle. It may be a better idea to collect the Brahman bull and artificially inseminate the Jersey cow if you really want this cross to happen. To add to what was mentioned above in the first sentence, a Jersey cow may be able to handle a Brahman bull if the bull was a yearling, not a fully mature 2200+ lb bull. To compare, Jersey bulls mature at around 1600 to 1800 lbs, considerably smaller than the average mature weight of a Brahmer. Thus, as mentioned above, if you want a Jersey-Brahman cross bad enough, it's possibly best to AI the Jersey cow with Brahman semen. Note, though, the bull from where the semen was collected better have high calving ease/low birth weight EPDs (Expected Progeny Differences) so that the Jersey will not have a difficult birth (dystocia) if she might if you paid little attention to such numbers.

From what I know, there was second the really bad snow storm in 1886-87 that resulted in thousands of cattle that froze or starved to death as a result of overgrazing and lack of winter feed. The first development, however was the outbreak of Cattle Tick Fever or Texas Fever in 1868 which originated in cattle shipped up from Texas, and was spread north and eastward, affecting and killing thousands of stock as the disease spread.
