These two elements in the periodic table are named after father and daughter pair. X (daughter) was discovered by Charles Hatchett in 1801. Hatchett found X in the columbite ore that was sent to England in the 1750s by John Winthrop, the first governor of Connecticut and named it columbium. There was a considerable amount of confusion about the difference between the closely-related X and Y (father) that wasn't resolved until 1846 by Heinrich Rose and Jean Charles Galissard de Marignac, who rediscovered the element. Since Rose was unaware of Hatchett's work, he gave the element a different name X.
Identify the two elements.
