Hi Patsy,
Anne Dalton is the only person with the Dalton surname to appear in Griffith's Valuation 1864 (this is the year the Valuation was done in Co. Armagh) She lived at Lissheffield, Loughgall. Quinns are all over the county so I will let you look for yourself as you might have a better idea than I do which ones might be connected to your family.
