Did Thomas Alva Edison have any children?

Edison had six children, three from his first marriage and three from his second: Marion (b. 1872)

Thomas Alva Jr. (b. 1876)

William (b. 1878) Madeleine (b. 1888)

Charles (b. 1890)

Theodore (b. 1898) Not-so-trivial trivia: When Theodore lived in West Orange, New Jersey, where Edison had had the laboratory that became the Edison Museum, the neighborhood was crowded, and parking spaces were scarce. Theodore designated a lot adjacent to his home for the free use of neighbors who needed a place to park.
