There is an (unsourced) family tree on Ancestry giving the year of death in 1857. This is quite probable as he is in the 1851 census but not in the 1861 census..
The other details have independent sources:
Charles Broad from tree Thomas / Steinhauser and associated families
Birth 14 Feb 1801 St. Kew, Cornwall, England
Marriage 21 Oct 1824 Cornwall, England
Death 1857
Father Robert Broad (1767-1841)
Mother Ann May (1767-1884)
Spouse Mary Mathews (1804-1864)
Any help tying up this loose end will be most gratefully received.
