While I am no longer doing family history research, I let you know that I have researched the Qualtrough family worldwide for much of the past 30 years.
Re William Qualtrough who married Margaret Corkill.
Len Faragher is correct in saying that they married in 1809
In checking my database, I have the following:

I have nothing on the parentage of Margaret Corkill and despite the fact I have Margt born in "poss Rushen" in 1790 does not mean that she may not have been born in Malew.... the information came to me from another source.
I do not have her parentage or any further info. Her death date was acquired from the Rushen MIs which I do not have access to right now... perhaps someone else could check that please if you have the Rushen MIs as that is where here age at death is recorded and thus the "c1790" for her birth year.
Please note that William Qualtrough remarried twice after Margaret's death to
1 Margaret Dougherty in 1821 at Andreas and they had 3 sons. Margaret D. died in 1841
2 Isabel Kinrade in 1844 at Jurby. No children from this marriage.
Hope this helps
Kind regards
