I just followed the links above and was brought back to here

I'm with gaffy - not sure with this one. I know she says born Ireland but that may not mean the family are Irish.

The witness at the marriage is Rachel Stubley. I can only find one living in Batley in 1841 1267/ 16/ 25
Also in Batley at 1841 1267 / 6 / 5 there is a John Hepworth 55 yrs a Woollen Weaver born in county with Margret 55 yrs b Ireland and Joseph 15 yrs b Ireland..
There may be no connection at all but you may want to look at the Hepworths.
Just seen a marriage of a Samuel Hepworth in 1838 - Batley, with a father John, clothier - the same as Fanny.
