From the book, "A History of the Pioneer Families of Missouri", by Wm. S. Bryan and Robert Rose, 1876, which is not always accurate but is a good base for doing research.

Captain Archibald Allen settled in Callaway Co., in 1822. He was born in Botetourt Co., VA., Jan 7, 1795, and served his country in the war of 1812. He was married in 1815 to ANNA GALBRETH, of VA., and settled first in St. Clair Co., Illinois, from whence he removed to Callaway Co., MO., at an early date. After the death of his first wife, he married NANCY HAMILTON, of MO., in 1858, who died also. In 1875 he was married again, to a MRS. BROWN, being at the time, more than 80 years of age. He died soon after. Captain Allen joined the Presbyterian Church in 1824, and was one of the first members of that organization in Callaway Co. He remained a consistent and devout member until his death.
