Margaret Devaney b.1825

[DavidGreenall110]

I'm looking for any information on the parents of Margaret Devaney born in Castlebar, Co Mayo around 1825?

I've picked her up on a couple of census records in Wigan from 1841 to 1891 where she states that she was born around that time. The marriage  certificate to William Unsworth from 1842 gives her as under age and her Father as Patrick Devine (Devaney) a Pensioner.

On the two census records for Patrick it gives him as a Chelsea Pensioner (blind) in 1851 and Agricultural Labourer in 1841.

Absolutely nothing on who her Mother is though!

Any help would be appreciated.
