Within the next two years, Beale made six more journeys across the country. On the second of these (July–September 1848), he crossed Mexico in disguise to bring the federal government proof of California's gold. After the fourth journey he married Pennsylvania Representative Samuel Edwards' daughter, Mary, on June 27, 1849. They had three children: Mary (1852–1925), who married Russian diplomat George Bakhmeteff, Emily (1854–1912), who married newspaper publisher John Roll McLean, and Truxtun (1856–1936).
