Just a month before receiving this appointment, he married Martha Hodgkins of Philadelphia, Pennsylvania on March 3, 1819. After returning from the expedition he spent several years surveying and building the Baltimore & Ohio and other railroads. He also became an inventor, receiving a number of patents for steam locomotives. When the United States Topographical Engineers’ Corps was organized in 1838, Major Long was given an important position in connection with it.
