Henry W. Greatorex lifespan?

I noticed that the People info gave Henry Wellington Greatorex's lifespan as 1813-1958. I had never run across any evidence that he lived past 1858 (though I have seen places where 1853 or 1855 is given as the year of his death), so I edited it to read 1858 (approximate). Perhaps after a bit more research I'll be able to pin him down to a year with high definitiveness. I've noticed that his birth year is also in a state of uncertainty, with many citations of 1813 and many others of 1816. Probably the most ridiculous "authority" I've run across, a website called "True Knowledge", changes his gender thusly: "Henry Wellington Greatorex was born in Burton upon Trent, England in 1816. She worked as a composer. She died in 1853 at the age of 37 years old." Wikipedia is of interest for its information about his wife, but does not look like it's very well documented as to his life. And it's not neutral in its POV; majorly disses the Sacred Harp types: "[HWG] did much to advance the standard of sacred music in the days when country singing-school teachers imposed their trivial melodies and the convivial measures of foreign composers on the texts of our hymn-books."
