3.  Anon.  1901.  Progressive Men of the State of Montana.  A.W. Bowen & Co., Chicago, IL (online at the University of Montana at Missoula Mansfield Library web site).  On p. 722:

JAMES H. LYONS... He was born in Tioga county, N.Y., on April 4, 1856, the son of Justus C. and Amanda B. (Southwick) Lyons, natives of Tioga and Orange counties, N.Y., who had six sons and two daughters.  His paternal grandparents were Henry and Sarah (Dean) Lyons, both born in Tioga county, where the former died in 1898 (sic 1889) at the venerable age of ninety-eight (sic 92) years.  The great-grandfather, Jesse Lyons, a native of England, emigrated to America in the early Colonial days, establishing his home in New York city, on or near the site of Trinity church. Justus C. Lyons removed to Wisconsin in 1864 and engaged in farming and dairying until 1883, when he removed to Montana and located on Mill creek, where he is still living on his ranch; his wife, however, passed away in 1874...

Most secondary sources show the father of Henry to be Justus LYONS.  Or was he Jesse Justus LYONS, as one of Henry's nephews was named?  These secondary sources, however, show the grandfather of Henry as another Henry LYONS (c1750-1780) of France and Orange Co., NY.  I've yet to find documentation to support either.
