Robert Musselman, Alamo defender, son of Peter Musselman of Shelby County, Ohio, was born in Ohio in 1805. He was a resident of Pennsylvania and served in the United States Army in the Seminole Indian War. While he was on active duty in Florida, his father died, leaving little or no inheritance. Instead of returning home, Musselman traveled to New Orleans and enlisted in the service of Texas as a sergeant in Capt. Thomas Breece's company of New Orleans Greys. He took part in the siege of Bexar and served in the Alamo garrison as a sergeant in Capt. William Blazeby's infantry company. Musselman died in the Battle of the Alamo on March 6, 1836.
