Hi Pat,
Looking at a f. tree given to me by Nigel Crowe, "Helena Mary Crompton" maiden name was "Perks" i.e she was a widow when she married T.A Corlett. I looked at the LDS site and found the following:

Robert Stevenson Crompton, age 34 = Helena Mary Perks, age 18, Ramsey IOM, 25 Jan 1870.

Helena Mary Crompton = Thomas Arthur Corlett, Douglas IOM, 12 Feb 1877.

Helena Mary Corlett = James Hardie, Lezayre IOM, 9 Jul 1879.

I haven't got cert's for any of these marriages so I haven't checked if they are all the same Helenas, but it would seem so.
Can I ask where you fit into the Corlett tree -just out of interest?
Best Wishes. Tracey.
