James Nowlan was born 1809 in England.
James Nowlan immigrated to America, intending to go settle. Ancestry.com offers a citation that he did indeed emigrate to San Antonio, Bexar, Texas. New Orleans was the closest port for a larger ship to discharge passengers. He then learned of the imminent revolution in Texas from the New Orleans Greys, so enlisted in the New Orleans Greys. James traveled to Texas as a member of the New Orleans Greys, with commander Capt. William Gordon Cooke. 
The company arrived in Bexar colony in time for the Siege of Bexar in latter 1835 (Oct.- Dec., 1835.) and was classed as a marksman serving in Cook's New Oleans' Greys. During that war (Siege of Bexar), James Nowlin was severely wounded at the Storming of Bexar, December, 1835). 
Following the Siege of Bexar, James Nowlin remained with the Garrison, most likely in the Alamo Garrison hospital. James Nowlin had a brother, John Nowlin in Texas, thus he prepared and left a will leaving any benefits to his brother. When the Siege of the Alamo started Feb 23, 1836, James Nowlin had not recovered, thus he was likely not able to do any fighting during the Battle of the Alamo. Nowlin was killed in the Battle of the Alamo, March 6, 1836. A memorial is in San Fernando Cathedral.
