On April 25, 1831, Bowie and Ursula Veramendi, daughter of provincial Governor Don Juan Martin Veramendi, were married. Upon appearing before the mayor of San Antonio, he pledged to pay Ursula a dowry of $15,000. Bowie claimed his age as 32 (he was actually 35), and the value of his properties at $222,800. That was greatly exaggerated relying on over valuation of property in Arkansas and Louisiana, and included some money still owed him.
In fact, Bowie had to borrow over $2,500 from his in-laws for a honeymoon trip to New Orleans and Natchez, Louisiana. After the honeymoon, Jim and Ursula Bowie settled in San Antonio.
