Thomas Hore of Ballymitty and Liverpool

I am trying to identify details of forebears and descendants of Thomas Hore (my great grandfather) who was born in Ballymitty but moved to Liverpool, where he married Kate Cloney from Waddingtown/Youngstown also in Wexford - just up the road in fact.

His mother Mary, wife of James Hore, came from Ballyhalbert County Down but I can't find details of the marriage (around 1848-50?) and so I have no maiden name for her.

If anybody local (or related!!) or someone researching the same families can help, I would be really grateful an really happy to get in touch.
