Isaac Heffron (1853-1928), born in Wales, immigrated to Galveston at a young age. In 1876, he married Clotilde Gillet, a native Texan. The couple had four children and purchased the house on Post Office Street, formerly Avenue E, in 1881. Heffron was a sucessful general contractor and served on the city board of alderman. As the family grew, Heffron rebuilt the Victorian house to include a second story, a new porch along the rear façade and an elaborate concrete balustrade for the front garden. The family lived in the house through 1901 when they moved to a new house on 17th St. The couple's daughter, Clotilde, and her husband, Andrew C. Falligant, lived here until 1913.
