Cox family Kilmastulla

I am seeking any information on a Cox family.  Margaret Cox baptised 10 January 1842 Ballina. Baptismal record states - Father Henry Cox,  Mother Kitty Murphy .  Townland Kilmastulla.  Sponsors William Cox and Margaret Murphy.  Subsequent marriage cert for Margaret states that her father Henry is a farmer.

I would like to ascertain where in Kilmastulla the Cox family lived or farmed.  Also seeking further details as regards Henry Cox and William Cox  such as birth marriage or death certs or any other info or other fanily members.

Thanks

John G
