Thomas was the son of John Bernard Westendorf and Mary Margret Parham, and husband of Jane Morrow (married May 21, 1873).
In 1880, he was married and living in Louisville, Kentucky, listed as a teacher and officer in a House of Refuge.
In 1910 he was heading a similar institution in Shelby County, Illinois.
Westendorf is perhaps best remembered for his secular song I’ll Take You Home Again, Kathleen, written while he was a school teacher in Plainfield, Indiana.
