I was searching on-line and came across a repository of documents dating back to the Republic of Texas.  I think it is sponsored by UT.  Anyhow, I found quite a few documents related to my great, great, great grandfather, Jackson Smith, co-founder of Jacksonville, Texas in Cherokee County.  In this document he is petitioning for a pension from his service in the Republic of Texas Army.  It states that he served in New Orleans and Galveston guarding against Santa Anna.
