Hi Tara. I have a Catherine Maher on the 1851 but am unable to link because there is no mention of her father.
I have checked the 1861 for the Rileys and the Mahers but cannot link any of them.
I also tried getting into Henry Street, Heaton Norris, on the 1861 but things seem to have changed again on FindMyPast and so I have given up on that (for now anyway).
Many thanks for the link to Kingsland, Herefordshire, but I know she definitely came from Ireland.
